You will get an infraction next time you gratuitously say any member of this forum is incapable of having their own thoughts, using your broken English, because he or she cannot agree with your obsessive pet theory (you apparently only discuss about that same topic in this forum, and you still dare to say other people are cukt menbers - some projection going on there, huh?). For now you will be rightfully the first person I will willfully ignore here. I do not like this self-righteous arrogance when you, I and everyone else are just amateues accompanying a science that is still very recent and full of holes (obviously).
You are the one member with more cultish sectarian behavior in this theead, and the oversimplified and clearly distorted interpretation of history and the data won't help you, either (you also seem to still think that a Y-DNA haplogroup is a people and also a cukture, and vice-versa, so of course your conclusions based on those premises will be biased).
But please do you really think we are talking about the origin of Iberian BB? Man, you sound confused. Not even the dating of the supposed replacement fits that. Nobody us claiming that Iberian BB came from Central Europe, but that CE BB-detived people entered Iberia later. And there are data, it is not just a speculation. You just have to interpret the data and e plain them. But the fact is there.
Quit that disparaging behavior now. People are not forced to think like you in order to be respected. You won't persuade anyone acting like that.
