This country the OP says they lived in where homosexuality was illegal, was it somewhere like Iran? Iirc, gay men there have a choice between prison (possibly a death sentence) or full surgical transition.
Btw, I do fully accept that tranwomen (and transmen) are what they claim to be. Transwomen are men who claim to be women, transmen are women who claim to be men. I don't see how their mental or sexuality struggles are any problem of mine. If transwomen are capable of knowing and accepting that they are not the same as women without expiring on the spot, then they can reframe the men's facilities as facilities for men and transwomen. Alternatively, they use a gender neutral facility. Women's facilities are for women and transmen.
There are people who claim to be a different race, one very famous one. By the 'be kind' logic of the OP she should have been affirmed not condemned.
Has the OP heard of erotomania? A deep seated belief that they are in a loving relationship with someone who is a relative, or complete stranger. Not always someone famous, they're the ones that hit the headlines. That the object of their affection doesn't reciprocate, is often fucking terrified, must cause them great mental distress. One woman, who was fixated on David Letterman, eventually killed herself. Shouldn't they be affirmed? Their dysphoria after all only damages one person not over 50% of society. It'll relieve their distress after all.
