Maybe I can. It seems Elezier was hurriedly trying to make the point that he's not affiliated with neoreactionaries, out of fear of the name of LessWrong being besmirched.
It's definitely true, I think, that Elezier is not a neoreactionary and that LessWrong is not a neoreactionary place. Perhaps the source of confusion is that the discussions we have on this website are highly unusual compared to the internet at large and would be extremely unfamiliar and confusing to people with a more politically-oriented mind-killed mindset.
For example, I could see how someone could read a comment like "What is the utility of killing ten sad people vs one happy person" (that perhaps has a lot of upvotes) - which is a perfectly valid and serious question when talking about FAI - and erroneously interpret that as this community supporting, say, eugenics. Even though we both know that the person who asked that question on this site probably didn't even have eugenics cross their mind.
(I'm just giving this as an example. You could also point to comments about democracy, intersexual relationships, human psychology, etc.)
The problem is that the inferential distance between these sorts of discussions and political discussions is just too large.
Instead of just being reactionary and saying "LessWrong doesn't support blabla", it would have been better if Elezier just recommended the author of that post to read the rationality materials on this site.
LessWrong is about the only public forum outside their own blog network that gives neoreaction any airtime at all. It's certainly the only place I've tripped over them.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
