Doesn't this problem gradually fix itself? For example, at the beginning I was interested in Moldbug's articles, but these days I just consider them boring. I have already heard the big picture; there is now nothing new, just reiterating what was already said; the lack of evidence or even clear explanations is very annoying, and I have already given up hope that it could be improved.
These days, if someone says something seemingly smart like "Cthulhu always swims left", my first though is: give me a definition of what the hell do you even mean by this, then give me an evidence that it really happens, and if you don't give any of it (which is my expectation based on previous experience) then just please shut up because you're wasting my time.
Speaking for myself, the neo-reactionaries had their chance (which I consider to be a good thing -- because I learned a few interesting things), and they wasted it.

I'm not sure, but my personal experience does mostly mirror yours. LW is not a stable group, though - there's a cycle of users entering and leaving, and the total number of active people at any given time is quite small.
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:
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.
