He just expressed in a way what Bruzmi was trying to propagate all the way. He is not trying to prove Illyrian ancestry for E-V13, he is desperately trying to disprove any connection of E-V13 with Thracians and propose Middle Age expansion of E-V13 so it better fits his narrative/imagination. I have seen several times from some circles pushing this narrative.
Why even give these people a platform for their existential crisis coping?
R1b-Z2705 (I am assuming that is what that person is referring to) is by all means more in sync with E1b-V13 in terms of expansion in the Balkans.
Bruzmi was very upset way early on when we got the first J2b-L283 MBA Dalmatian sample and did not really change after Patterson/Reich et. al and the Daunian paper. He is definitely still pushing in a very odd obsessive way an entire Illyrian origin for E-V13 which aDNA does not support whatsoever.
The problem I see with him and many other irrelevant nationalistic people is a very science refusing mentality: everything has to be narrative-fitting.
