Ngo has been playing footsie with race science since as long as I have been skimming LW.
The irony is that in any "normal" space (i.e. not Stormfront) he would have been booted out toot sweet for being a racist. On LW, he's tolerated, even celebrated, but apparently not enough for his liking. It's not enough that he can spew race science unopposed by any meaningful reaction, everyone else has to take his position.
Edit
the piece he authored 6 months ago and references here is a doozy too

The overwhelming majority of successful civilizations throughout history have been nation-states, at least to some degree, which should be addressed in some capacity by any argument claiming that it's a suboptimal way to organize a society.
uh... the Roman Empire was a nation-state? Holy Roman Empire? (ok not as good an example) Ottoman Empire? Basically all of India pre-Brits?
A huge part of the French Revolution was the codification of France as "The Nation" of French people, not as the weird personifciation of the king. But somehow I suspect that bringing up the French Republic won't be hugely popular in this crowd.
