I'm talking about criticisms of demographics and identities of non-marginalized groups that actually frequent Lesswrong.
The Cathedral, to use Moldbug's terminology, is certainly a non-marginalized group and LW is full of its adherents.
Agreed, but we devote plenty of time to criticizing it, don't we? (Both reactionary criticism, and the more mainstream criticisms of the media/academia culture)
But the thing about the reactionary lens, especially Moldbug, is at the end of the day they side with the people in power. Moldbug even explicitly states as much. A central theme of his work is that we shouldn't keep elevating the weaker and criticizing the stronger, thus creating endless revolution.

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.
