Please forgive my error, I think you are the first I've personally met under 50 that has embraced the label. I must admit that there is a bit of me that twinges with the carrying on of it but also recognize that's partially a me problem. Trans medicalism and the distinction of having to possess a fully changed physicality to be accepted by both outside and inside the trans community has traditionally been the hammer weilded by binary trans folk against the non-binary trans community as a "you're not a REAL trans person" style accusation so it generally makes me personally a bit skittish hearing "trans sexual" from anyone my age or younger.
But it's largely the fault of pressures that effect us all. When someone is under pressure to glean any amount of respectability to survive cracks form in solidarity and some will take the opportunity to point to the next person down the line that's even harder to understand and go "Oh, I'm nothing look at them. Aren't I just reasonable by comparison? " I think nowadays I see more growing solidarity inside the community than a decade ago but the memory of those divisions and the language used still makes me twitch.
But inside the non-binary trans community we have a similar bit of friction with people who use it/its pronouns... Like for a lot of us that is very VERY unwelcome because it has dehumanizing connotations but for some that is legit what they feel best supported by in their experience. I know some inside the group have the gut instinct to feel kind of undercut by that minority inside our minority for creating a "bad" example to the straights but the world is full of nuance and it can probably afford some extra.
It's just unfortunate even when there's a lot of us around in a place a lot of cis folk don't know the very basics of what is common good practice versus what is kind of a special case. It drives the instinct to self police more then we should have to.
