Scott Alexander, by far the most popular rationalist writer besides perhaps Yudkowsky himself, had written the most comprehensive rebuttal of neoreactionary claims on the internet.
Hey Trace, since you're undoubtedly reading this thread, I'd like to make a plea. I know Scott Alexander Siskind is one of your personal heroes, but maybe you should consider digging up some dirt in his direction too. You might learn a thing or two.
Would also be great if the article he talks about doesn't start with "I no longer endorse all the statements in this document.[emp mine] I think many of the conclusions are still correct, but especially section 1 is weaker than it should be, and many reactionaries complain I am pigeonholing all of them as agreeing with Michael Anissimov, which they do not; this complaint seems reasonable. This document needs extensive revision to stay fair and correct, but such revision is currently lower priority than other major projects. Until then, I apologize for any inaccuracies or misrepresentations."
