That's speculation by "Rational Wiki", a far from rational and highly politically biased group that defames everything and everyone as "racist" that doesn't fit their world view. This has in the past included attacks against highly respected people like Scott Aaronson and Scott Alexander. They do not focus on evidence-based arguments, as real rationalists would. They don't calmly post peer-reviewed studies like Paolo Shirasi. Their Modus operandi is a) doxxing and b) to slander people with the label "racist".
But reality is what it is. It doesn't care whether someone labels a hypothesis as racist or not. The only way to grapple with reality is to find out what it is.
I don't read RationalWiki pages for analysis, just for the receipts they have, which was the point of that link. You've cited a pseudonymous racial supremacist.
I cited someone who posted empirical evidence from a lot of peer-reviewed studies. Slapping the defamatory label "racial supremacist" to anyone who cites evidence one doesn't like doesn't change anything. Apart from that, a "supremacist" usually refers to someone who thinks his group is the best one, but we have no indication that he is Ashkenazi Jewish or even East Asian.
