The closest I come is my attraction to men getting blocked by what looks like PTSD.

Don't feel the need to try to force yourself to be attracted to men (not saying you are), because the majority of men are scummy (the majority of women aren't that great either, but my point still stands), and if you're put-off by a man, you should trust your instincts. I have plenty of male friends, and I meet men all the time (at school) who I just don't like right away, usually because their personalities are, as you said, "off-putting at best and threatening at worst", but most men who act like this are just putting on an act, and are really bitches. If confronted, they show themselves to be cowardly.

[Men] tend to be rather emotionally-contained/reserved.

Lol, not in my experience. Men tend to express emotions they deem feminine, which is basically all positive emotions, less than women do. That's what I mean when I say I prefer men with a more "feminine" personality, even for friendships. However, men express negative emotions a lot more than women do, such as complaining and yelling, since those behaviors in boys aren't punished or are mildly punished, as opposed to little girls, whose anger people attempt to stamp out.

women often have a penchant for the kind of "bleeding-heart"ism that makes them prone to becoming SJWs/trans-dupes

Yeah, I think we're in agreement here. This is why I prefer a partner with some masculine and some feminine traits. A kind person who expresses themselves and stands up for themselves, but has a couple band-aids on their heart lol.

if I find a woman attractive, it's hard not to compare myself unfavorably to her

Thankfully, I broke free from that a few years ago. I simply stopped giving a fuck about feminine beauty rituals, and no longer compare my looks to anyone because why tf should I care as long as I'm clean? Partner-wise, I would not want someone who dresses hyper-feminine and wears makeup, since I tend to just feel bad for those people. They can be really attractive tho lol, but someone who's comfortable in their own skin will be worlds more attractive to me.

"lesbian U-Haul"

I've only experienced something like this once. I won't go into too much detail, but I chatted with a girl (I was quite young) for one day on a dating app, and she needed somewhere to stay for a night because of a bad housing situation. I was weirded out, and nothing remotely sexual/romantic happened. She wanted to stay longer, but I asked if there was anywhere else she could go, and there was. I was a lot younger back then, and it wasn't my house. Hope everything went ok for her.

Lol yep, I once knew a woman who was like that.
