The majority of Illyrian samples aren't "Illyrian". The term Illyrian was not applied to those areas until the times of the Roman Empire.
Maybe you should learn some basic history instead of haplobro science.
It was applied before that actually by the Greeks referring to tribes north of them. Although it's true the term came to be more used during the Roman period. And how are they not Illyrian ? That's where Illyrians lived. Strabo referred to them as Illyrians. Maybe proto-Illyrians then would be the right term. There is also cultural material. And there were Celts, Thracians and other people that settled there too.
It's also funny how the guy claims J2b2-L283 is not linked to proto-Albanians when it actually is.
