I had thought lesswrong "merely" has a plurality of racists HBD'rs but judging from the total lack of comments calling out his racists bullshit and the majority of comments advising hiding your power level as a practical matter, I guess lesswrong is actually majority HBDers at this point.

Also, one of his followup comments (explaining why he doesn't want to just stay mask on like the other lesswrongers) is pretty stupid and gross:

Thanks, good comment. The quick low-effort version that doesn't require actually writing the posts is that without taking heritable IQ into account, I think you will be confused about:

1. Various ways in which post-apartheid South Africa is a bad place to live.
2. Why so many countries have market-dominant minorities.
3. Why Israel is so good at defending itself even against far larger countries surrounding it (and the last few centuries of Jewish history more generally).
4. Why the growth curves for East Asia and Africa looked so different over the last century.

1 and 4 show the continued willful ignorance about the harmful effect of colonialism and neocolonialism. The first part of 3 is obviously huge amount of material support from the US. I don't know what 2 is talking about, I assume he's got some stupid and racist interpretation of various historically contingent things.
