There is a fundamental misunderstanding here of how gene flow and language can interact.
Here is a very plausible scenario based on the facts as we now know them. The I2a Mesolithic people of the Balkans, who may be of a completely different branch than the I2a people who lived in the north or on the steppe, spoke goodness knows what mesolithic hunter gatherer language. As we now know, during the Neolithic at the latest they were joined by E-V13 and J2b people, who spoke who knows what farmer/cow herder language. I'm not even going to get into a discussion of it because it's irrelevant from which language family it derived; it got there in the Neolithic. During the Bronze Age, R1b people arrived and imposed Albanian, their Indo-European language, on the I2a, E-V13, and J2b people who were already there. Add in some minority later arriving "Dinaric" I2a and some R1a, et voila, you have the Albanians.
You should be aware that most people who read this site have at least a modicum of knowledge about genetics and archaeology and history, and they will not be convinced by these kinds of a-scientific and illogical arguments.
Angela, I just try to severity. You know, I'm supporter of Anatolian hypothesis and not Kurgan hypothesis. Although Kurgan hypothesis possible still has more support, I think science will round off Anatolian hypothesis. New Zealand scientists in basis of Anatolian hypothesis and using new methodology and computer modeling came to their classification of IE languages. According them:
We can clearly see here first split Hittite and rest of IE, second split Tocharian languages and rest of IE, third split Greek and Armenian and rest of IE etc. We can see split Albanian and Indic and Iranian languages. We can see split Balto Slavic and Western Languages (Celtic, Germanic, Romance). Albanian even today has some similarities with North Iranian languages, (even Pashtun and eastern languages), there are languages Eastern Anatolia and Caucasus, even Caspian. If we speculate it is possible that once existed Proto Indic Iranic Albanian language. It can be possible if R1b ht35 carries speakers of Proto Albanian were more eastern comparing to R1b ht35 carriers, speakers of Proto Armenian.
What is dispute here?
1. There is a scientific basis: Anatolian hypothesis
I would like that Albanians or someone support Kurgan or some third hypothesis.
2. There are scientific papers: for model it is Grey, Atkinson, and they published this in more papers.
Of course there are different models. But everyone use one of them.
Why I say scientists from New Zealand. Because all what I give any "Slavic" source Polish, Bulgarian, etc. they claim Slavic propaganda. I have problem because serious scientists from more countries can't use, and their papers. But to be honest, if every scientist from Poland, Bulgaria, Slovakia, Czech Republic, Ukraine etc. is propagandist. I can argue that they are serious scientists with serious papers, but "for peace in home" I will not use them, at least not quote.
Plus there are more sources, papers scientists about link Albanian with Armenian, etc.
3. There is genetic evidence. We know Armenian haplogroups and populations in Caucasus and Eastern Anatolia. We have now and Armenian samples from BA, and they confirm R1b ht35 Armenian haplotype.
What I speculate? For example movements. Who knows? There is hypothesis about movement of Armenians from Balkans to Anatolia, but Armenian scientists strictly deny it. Therefore is important to read paper about it which will be published this year.
In any case Albanian speakers came to the Balkan.

I never defended someone to give his or her views. Everyone can say what he or she thinks, of course you're right some good practice should exists.
And I make mistakes. I like when someone notices it. When it is case I say that it is mistake. Who writes makes mistakes. One Englishman once told me that if I want to not make errors I must think in English. But I can't think in English.
