That's how I've arranged my life. I live in a civilized neighborhood in a civilized city.
I actually grew up in Hawaii, where the thing for young men to do was find the nearest young male "haole" (white) to harass, threaten, or beat.
That's one bit of violence that the blogger likely missed out on. Young men looking to prove their manhood often look to find other young men from some unpopular subgroup to victimize. But that's people with penises being victimized, so what the hell does that matter?
One of the unfortunate things about SJ as it currently exists is that they don't want to hear that privilege is local. Intersectionality is a step in the right direction, and I hope things will keep getting more fine-grained until it gets to what happens in individual lives.
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.
