What "bio"? So far I have only seen far left dominated opinion pieces, who obviously hate that he engages with taboo topics like race and IQ.
Anyone who contradicts this notion that some races are better than others and ergo those other "mud" races need to be exterminated, is too far left for retards like you. Go bait someone else.
That's not the right way to think about it. It is an empirical question whether there are significant heritable IQ differences between populations with similar ancestry. If such differences exist, then this is a very important fact to know about the world. We always want to believe the truth, whatever it may be. Labelling possibly true hypotheses as racist doesn't help. Ethical questions are different from empirical ones.
