Moral, like language, is a human invention and is highly cultural. Children aren't born with values, nor are they born with elements of language (except maybe those already acquired in the womb, as foetuses can hear).
Children don't need to be explicitely taught all moral rules. They can understand them by themselves, intuitively (i.e through unconscious reasoning and learning), but it isn't from an innate knowledge, as this doesn't exist.
I think we are just arguing about the philosophical issue of innate ideas (rationalism) vs acquired ones (empiricism ) . Some philosophers (Descartes...) believe that the mind can create entirely new ideas unrelated to experience, while others (Locke, Hume...) think everything is based on experience. I believe in the latter, while you and Chomsky are followers of the former conception.
It is interesting, isn't it? I do recall once reading a cross-cultural study of morality which compared middle-class American kids with Hindu-Brahmin culture in India and found the Indians consumed with matters of social and religious convention, such as eating codes (the worst violations being something to the effect the day after his father's death, the eldest son had a haircut and ate chicken) while the American children were predictably fixated on questions of social and interpersonal justice or humanitarianism (violence, abuse, fairness, trust, equality, etc.) The interpretation being that in the Brahmin community studied, rules were seen as part of a natural religious order, found rather than founded by people, which therefore take on a level of transcendence only imagined by most Western children.
And here is an excerpt from a summastion I found in a paper on Chomsky's supposed or not rationalism/nativism/pragmatism, etc.

The nature of knowledge of language, which is closely tied to human knowledge in general, makes it a logical step for Chomsky to generalize his theory. The linguistic theory for special 'Plato problem' can be applied to 'Plato's problem' to knowledge in general, providing that an empirical evidence of such problem for a certain knowledge. He says, his innate principle includes syntax, phonology, and morphology, and semantics. By 'semantics' he means the study of the relation between language and the world ?Ein particular, the study of truth and reference. (8) At the same time, he also generalizes his idea of UG, especially the process of parameter determination in acquiring a particular natural language for a subject. "This result of this process of parameter determination and periphery formation is a full and richly articulated system of knowledge. ...The same may well be true of large areas of what might be called 'commonsense knowledge and understanding'". (9) The first generalization, generalization of 'Plato's problem' to knowledge in general, is correct. The second generalization, seems to us, is too hasty. The advances in neural science and mathematics have produced new theory on complex systems. For a vast complicated system as human brain, which is tremendously flexible and which processes abstract concepts at many different levels, the theory of parameter determination over-simplifies the problem we are facing.

Chomsky proposed, in our view, a plausible theory of language. The different approaches between E-language and I-language may be similar to the Brahe and other's observational astronomy, which collected a vast body of data, and Ptolemy, Copernicus, and Kepler's model of planetary motion, even though the details of the model might be questionable. Chomsky's first generalization is also a legitimate step. But his proposal of "innate ideas" has been resisted by some empiricists, and he is characterized as rationalist. In our view, those empiricists make a mistake. In order to clarify this issue we will cite Chomsky's statements in spite of somewhat redundancy.
Chomsky attempts to develop a theory of linguistics as a discipline of natural sciences or physical sciences, which are empirically based. He specifically objects to 'Abstract-linguistics' (10) and he maintains that the boundary between linguistics and natural sciences will shift or disappear. The theory of mind aims to determine the properties of the initial state So and each attainable state SL of the language faculty, and the brain sciences seek to discover the mechanisms of the brain that are the physical realizations of these states. (11) Eventually, the linguistics and the brain science will converge. Chomsky uses the term 'mechanism', which refers to the physical mechanism. (12) He says, one task of the brain sciences, is to discover the mechanisms of brain that are the physical realization of the state SL. What he means by physical realization is the physically encoded mental state on the brain. "In contrast to E-language, the steady state of knowledge (I-language) attained and the initial state So are real elements of particular mind/brains, aspects of the physical world, where we understand mental states and representations to be physically encoded in some manner." (13) Chomsky's UG is biologically determined (14) principles too. Chomsky seems to use 'physically' and 'biologically' interchangeable. In this aspect Chomsky's universals that are biologically realized and physically encoded in brain, are different from Descarte's innate ideas.
Chomsky rejects the fictional and abstract objects and, especially, rejects the suggestion that knowledge of language should be taken to be an abstract "Platonic" entity. He says; "Knowing everything about the mind/brain, a Platonist would argue, we still have no basis for determining the truths of arithmetic or set theory, but there is not the slightest reason to suppose that there are truths of language that would still escape our grasp." (15) He differentiates linguistics from mathematics and emphasizes the empirical aspect of linguistics and its relationship to brain sciences; therefore, the justification of his theory is not only a theoretical matter, but also an empirical that relies on the results of brain science. Based on Chomsky's positions on the nature of his linguistics theory, we conclude that he has been mistaken as a rationalist. In the next section, we will discuss some of the debates on this subjects and other related issues.

One of the reason that he is regarded as a rationalist might be that Chomsky tries to differentiate himself from the linguistic behaviorism and he emphasizes some of reasonable core of "rationalism" to make a statement that my "sausage-making machines" (16) is not tabula rasa, but has complex, dedicated parts and structure. The other reason is the tradition of the rationalist philosophy of language, philosophical grammar. (17) He is not satisfied with the explanatory power of the descriptive grammar. Philosophical grammar is "typically concerned with data not for itself but as evidence for deeper, hidden organizing principles,..." (18) However, it may be surprising, his term 'rationalism' is equivalent to 'natural science', He states that the issue of rationalist philosophy of language "is not between descriptive and prescriptive grammar, but between description and explanation, between grammar as 'natural history' and grammar as a kind of 'natural philosophy' or, in modern terms, 'natural science.'" (19) He particularly criticizes the lack of physical, empirical aspects of Cartesian rationalism. (20)
Rationalism stressed the power of reason as opposed to empirical facts and used deductive reasoning as the basis for their knowledge system. Chomsky's theory is an empirical science and his method is largely based on linguistic empirical data. Therefore, Chomsky's theory is not rationalist in the classical sense. Some of his opponents (Quine, Wells) confuse what Chomsky is claiming and what he is doing. (21)
Understanding of Chomsky's position on those issues, some of the objections to his theory become automatically invalid, Goodman (22) raises a question. How does Chomsky start from some subtle difference in linguistics and then moves on to innate ideas? "I know what a horse with spirit is, but not what the spirit is without the horse." (23) This UG is not something that "a spirit without a horse" at all.
On the other hand, Chomsky's theory is empirical, but different from behaviorism linguistics. On the issue of "innate structure", Harman does not accept Chomsky's theory of innate structures. He said: "I view linguistics, it is closer to both anthropology and the behavioral sciences than he would apparently allow." (24) Quine argues: "This indisputable point about language is in no conflict with latter-day attitudes that are associated with the name of empiricism, or behaviorism. (25) There are two major differences between behaviorism and Chomsky's theory. Behaviorism treats a complex system as a black box, a functional mechanism. If two black box function exact the same, behaviorism and functionalism regards them exact the same. This is Quine's so-called 'enigma doctrine'. He says, "English speakers obey, in this sense, any and all of the extensionally equivalent systems of grammar that demarcate the right totality of well-formed English sentences." (26) However, Chomsky's "theories of grammar and UG are empirical theories" and his systems of grammar is physically encoded in some manner. The development of brain science will discover the very physical structure of human brain, and there can be only one of a set of "extensionally equivalent systems of grammar" is correctly attributed to the speaker-hearer as a property that is the same as that is physically encoded, where some other one merely happens to fit the speaker's behavior but does not correctly represent the physical facts. The second difference is reflected by the relationship between I-language and E-language. E-language, as the traditional behaviorist linguistics, deals with steady-state language, or mature language; while I-language in Chomsky's theory specifies not only the internal characteristics of language, but also deals with a dynamic process, language acquiring process, from initial state So to the steady state SL. (27) E-language is independent of a individual's history, while I-language explains the language aspect of individual's history. This dynamic process puts more constraints on the characteristics of the languages. I-languages may reach the same steady state SL and realize the steady state languages that have "extensionally equivalent systems of grammar"; while these I-languages may specify different dynamic processes that reach SL. These processes differentiate I-languages one another and some of them can be proved to be wrong theories regarding the language acquisition process. Therefore, extensionally equivalent systems of grammar in the traditional grammar sense is not necessarily equivalent in terms of I-language.
Nagel questioned whether the initial contribution of the organism to language-learning is properly described as knowledge. (28) Dummett questions the concept of unconscious knowledge. (29) He holds that there is an extremely important innate capacity but it would not called innate knowledge in either case. Chomsky introduces "cognize" in trying to resolve the issue, which we think it might be superficial. In computer science, a computation can be either realized through software, which is written in computer language, or through hardware, which is built by the logic circuits composed of physical parts. Both functions exactly the same. If we can do an extrapolation or analogy, ideas might be realized through abstract symbol systems or through neural-network. The two mode of structures may have effects on the recognizability. This is a speculation. But our point is that UG is proposed as hypothesis, and if the 'notion of structure' is correct, other hypothesis may be assumed on what kind of structure is and how the structure operates. The final settlement relies on new development of brain sciences.
UG as a hypothesis raises questions about to what extend the hypothesis correctly captures the structure of brain. Danto says:
"...to what extent does the innate structure of language formation sink into the world, giving it linguistic form, or the form of our language(s)? So far as LA is universal, we live perforce in the same world if the structure of our world reflects the structure of language. Obviously, something produced by means of a different LA would not be recognizably a language, nor would the world correlative with this, if there is this correlatively, be recognizably the world. A wholly different language or a wholly different world would be unintelligible, but is the very idea unintelligible?". (30)
Chomsky treats the innate idea as a fixed form (common grammar hypothesis), which resembles rationalist doctrine of ideas; while his attempts in providing a natural science of language is not consistent with such hypothesis. In this aspect, Herbert Spencer (Principle of Psychology) might be right that innate ideas, such as adopt form of thought, like the perception of space and time, or the notions of quantity and cause, which Kant supposed innate, are merely instinctive ways of thinking; and as instincts are habits acquired by the race but native to the individual, so these categories are mental habits slowly acquired in the course of evolution, and now part of our intellectual heritage. In Spencer's word, "the inheritance of accumulating modifications". If this is correct, chimpanzee and human ability in communication and maybe language can be bridged in principle, and the study of chimpanzee's brain would help to discover the innate structure physically encoded in a certain manner too.
