Discussions like this often end up at WW2 and that's not what I'm saying here, but Germany in the 1920s was essentially the Gay/Trans hub of the world until it wasn't: https://www.netflix.com/title/81331646.
But even that's not the beginning of 'trans'.
The reason trans isn't 'flying under the radar', isn't because trans people got too proud. Its because one political party decided to shine the magnifying glass to turn trans into a political issue.
How many do consider reasonable to sacrifice in the name of political expedience?
Trans women until VERY recently were forced to go into prostitution and were excluded by the wider society. Trans people were not force teamed into any war, or rather, this is partially right, they were forcefully forced to pick a team by the side that aims to take away their bodily rights, protections, and mark them as undesirables again.
I hope you make it out here one day, if you haven't already.
