You are so upset that you cannot explain clearly your point of view. Are you telling us IE tongues waited IA to reach western Europe?
The BB phenomenon is very curious and we cannot be sure its first promotors were IE's, here I can agree with you, without any certainty. But the massive male-biased Steppic genetic introgression into Europe is proved and preceeded IA by large.
I don't buy the Davdisky 's theory linking BB's and CWC at the origins, and t the same time, we are not sure todate that Y-R1b-DF27 was associated to first BB. What I'm almost sure is that DF27 as other P312 and close upstream R1b came from at least East-Central (north- or peri-Carpathian?) Europe if not directly from Steppes - see the L11 distribution in Eurpe. And for language, the link between northern (acculturated?) R1b BB's and some kind of proto-Ligurian-Celtic-Italic-... IEan languages seems the most evident with our todate knowledge.
In fact I see more witches than fairies in this thread.
Upset? why would I be upset?
My point of view is very clear, the genetic continuity of R1b-P312/Df27 from the beginning of the BB culture to the Iron Age peoples in Iberia and southern France is enough proof to think that the BB culture did not speak an Indo-European language.
And I am also saying that the Indo-European languages (Celtic and Latin) entered Iberia in the Iron Age. Do you have any evidence that makes you think that they entered in the Chalcolithic or Bronze Age? If you have it, tell us what it is and we will be able to value it.
Massive male-biased Steppic genetic introgression into Europe is proved? REALLY?- The first R1b-M269 in Europe are in Bulgaria (Smyadovo-4.500 BC), and Spain (ATP3-Atapuerca-3.400 BC). Then you have 3 Neolithic farmers R1b-M269 in Switzerland buried in dolmens (2.730-2.620 BC), two of which have no autosomal steppe signal. You have VK531 in Norway R1b-P297 (2,400 BC) with no trace of steppe ancestry - for you this is a massive invasion of the steppes.... Let's imagine that you are right and that the origin of P312/Df27 is in the steppes, do you think that those lonely explorers buried in dolmens were able to change the language of western neolithic cultures?
We are not sure todate that Y-R1b-DF27 was associated to first BB- YES WE ARE

These are the first two Df27 found in Europe. The first one buried in the entrance of a dolmen with Ciempozuelos style ceramics, and the second one buried in a cave with Pyrenean style ceramics (decorative motifs identical to Ciempozuelos). Have you found Df27 in Eastern Europe or the steppes?
Are you sure that DF27 as other P312 and close upstream R1b came from at least East-Central (north- or peri-Carpathian?) Europe if not directly from Steppes-To say that you need proof and to date the Harvardians who have been desperately searching for L51/L151/P310/P312 in the steppes for five years have not yet found it. We will have to wait for them to do so to accept the Kurgan theory as formulated by Haak, Reich and colleagues. For the time being, they are only fairy tales.
You see witches and I only see people who only have steppes in their brains as in so many other internet forums.
