It’s apparently supposed to make a distinction between trans people before/after bottom surgery. I doubt that’s a common use for that word, but I still have a few points against that specifically:
- I don’t think it’s ok to make a distinction those in this way
- It straight up ignores that not everyone wants bottom surgery
- It’s not even the way ‘-sexual’ is used normally.
Most people just use it interchangeably with transgender to my knowledge.
If I hadn’t heard of it in context it’s commonly used in, I would think that it’s the attraction to trans people.
Idk if I’m making any sense here, I suck at saying/writing things that do
I think you might be a bit confused, transexual wasn’t meant to be used as a label for sexuality, it was meant to describe a person’s sex/gender/body.
The last part of your post is sensible and I agree, but while you may not do it, many people do use immutable characteristics as descriptors when speaking about another individual out of genuine ignorance. It’s especially often when the individual being spoken about is some flavor of minority. (“My gay cousin…”, “My black friend…”)
