I've got a lot of sympathy for your situation-- I spent a lot of time freaking out about the complex emotional abuse that anti-racists/certain kinds of feminists go in for.
Still, I found it useful to learn something about assessing the current risk level of an attack just so I don't go crazy-- they've spread a lot of misery and they may eventually be politically dangerous, but they aren't imposing the sort of immediate visceral threat you're reacting to.
We haven't begun to see the next stage of the fight (or at least, I haven't seen anything I'd call effective opposition to the emotional abuse), but I recommend steadying yourself as much as possible.
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.
