Very literally a trans woman is who kicked off the Stonewall Riot in 1969. This was the beginning of a sea change for the LGBT community, not just in the USA but worldwide. So no, we've always been here. I mean no offense but your inability to see us comes from your own lack of perception. And your hostility to being invited towards empathy says more about you than us, I'm sorry.

This isn't even going into centuries of cultures subverting gender roles or whatever, I doubt you care about that. But we're here. We've always been here. You'd probably know more about us being here if the
very literal Nazis didn't
very literally burn books in 1933 from the Institute of Sexology.
So yeah maybe don't use the word "trap" if you don't want to make us recall trauma our community has suffered. I'm sorry if that's somehow a huge ask.
EDIT: Also we are part of your fandom. I love Minato, Mahiro, Nayuta, everyone. You're just going to have to accept we exist, we share a fandom with you and will say "ow" if our toes are stepped on. Because that is the appropriate response to having your toes stepped on.
