I sometimes regret that so many of my attempts to talk about trans issues end up focusing on psychological sex differences. I guess I'm used to it now, but at first, this was a very weird position for me to be in! (For a long time, I [really didn't want to believe in psychological sex differences](/2021/May/sexual-dimorphism-in-the-sequences-in-relation-to-my-gender-problems/#antisexism).) But it keeps happening because it's a natural thing to _disagree_ about: the anatomy of pre-op trans women is not really in _dispute_, so the sex realist's contextual reply to "Why do you care what genitals someone might or might not have under their clothes?" often ends up appealing to some psychological dimension or another, to which the trans advocate [can counterreply](https://thingofthings.wordpress.com/2018/06/18/man-should-allocate-some-more-categories/), "Oh, you want to define gender based on psychology, then? But then the logic of your position forces you to conclude that butch lesbians aren't women! _Reductio ad absurdum!_"
