A long blog post explains why the author, a feminist, is not comfortable with the rationalist community despite thinking it is "super cool and interesting". It's directed specifically at Yvain, but it's probably general enough to be of some interest here.

I'm not sure if I can summarize this fairly but the main thrust seems to be that we are overly willing to entertain offensive/taboo/hurtful ideas and this drives off many types of people. Here's a quote:
In other words, prizing discourse without limitations (I tried to find a convenient analogy for said limitations and failed. Fenders? Safety belts?) will result in an environment in which people are more comfortable speaking the more social privilege they hold.
The author perceives a link between LW type open discourse and danger to minority groups. I'm not sure whether that's true or not. Take race. Many LWers are willing to entertain ideas about the existence and possible importance of average group differences in psychological traits. So, maybe LWers are racists. But they're racists who continually obsess over optimizing their philanthropic contributions to African charities. So, maybe not racists in a dangerous way?
An overly rosy view, perhaps, and I don't want to deny the reality of the blogger's experience. Clearly, the person is intelligent and attracted to some aspects of LW discourse while turned off by other aspects.
I think this is a bit too black and white. There is not a well-defined group of ideologically homogeneous reactionaries which you could just get rid off. Rather, a significant number of LW contributors are sympathetic, to various degrees, to a variety of reactionary positions. I'm not a monarchist and I'm not a fan of Moldbug (why doesn't he just say what his claims are and then offer what he sees as the supporting evidence for them? why the wearisomely verbose exercises in smugness?). On the other hand, I am interested in HBD issues and I am sympathetic to some ethno-nationalist causes (e.g. the desires of the current majority population of Israel to remain the majority population of Israel). Perhaps more to the point, Yvain has spent a lot of time criticizing reactionary philosophy but he has also made it clear that he agrees with significant parts of it. Indeed, a person being upset by his posts is what triggered the current thread.
How about that good old Solzhenitsyn quote:
What parts of neo-reactionary philosophy does Yvain actually agree with? He says at the end of the anti-reactionary FAQ that he likes how they're utopian, but then says he's actually more interested in other utopian schemes.
