Not only this, homo sapiens in Europe and Asia mixed with neanderthal which was hugely genetically different, this resulted yet again in huge advantaged from human populations outside of Africa.
And lastly, the less genetic diversity an ethnic group has, the most genetic susceptibility to diseases. The most healthy European countries are actually quite mixed. Sorry about this.
>I refuse to believeThat's where you fail my friend, educated should be about understanding. Not about believing, once you understand you will know. But I can only tell you things, if you fail to understand how your ideas are clearly invalid and desperately cling to them like other white nationalists then there isn't anything more I can do for you.
