Also, as a matter of community strategy, I'll note that citing sources like VDARE.com with apparent approval might make people of color feel unwelcome on LessWrong, even if the specific quoted claims are correct — just like citing Roissy might make women feel unwelcome even if you only quote true claims he has made.

Thank you for saying this. You may need to (I won't say "like to") read up some of the past race-vs-IQ discussions on LessWrong and work out how to discourage people from saying boneheaded scientific-racist shit in them, c.f. last time I dared note this was actually a serious problem. (The recent downvoting into oblivion of the "race realist" post, and of the author's frothing responses in the comments, was most encouraging IMO.)
