From the outside, "creepiness" looks a lot like "ew, he doesn't play the social game on my level and should therefore be reviled and shamed". I understand that there's more to it, but that particular aspect looks downright evil.

I don't think this is usually the case, especially not within the context of rationalist gatherings. I have had several interactions with people on (or who seem to be on) the Autism spectrum, and I have not ever felt creeped on by them, and most of my interactions have been positive with them. While it seems that low status men are more likely to act creepily, I do not automatically feel this way about someone who is low status, and I do feel creeped out by high status people who disrespect my boundaries. So I don't think this is a significant part of creepiness.

So, can someone remind me why I should go out of my way to adjust myself to be women-compatible? I've already given up on 95% of people, why not another 50% (actually more like 10%) of the remainder if it saves me trouble and improves my life?

As a woman, I would rather avoid people like you anyway. Hope that helps.
