yet again implying Europeans are heavily mixed

I didn't say this. It seems your arguments (before and now) focus mainly on predominantly white vs predominantly non-white genes in Europeans. I'm not really addressing this. My main argument is that there is a mixture of ethnicities, albeit less in some and more in others, but naturally Europeans are predominantly white-skinned, and regarding the Semitic or Hebrew groups, one would have great difficulty showing that these people are any different from Medeterranean white-skinned groups, even while appreciating that some Semitic groups try to marry ONLY Semitic people.
