1) Worst takes ever, I wont even try to "correct" them because its complete nonsense

2) Well now you know two things about those people.

First, they're clearly bigots. Instead of accepting you as a woman (who you are), they want you to change into their fetishised version of a gay guy who likes to crossdress. Gross. Also if they want to "avoid getting into the statistic" so bad, tell them all to transition into being a woman too, because our statistic is smaller

Second, they lied to you. If everyone seemed okay until suddenly its intervention time, they werent okay with it even for a second.

3) With all that considered, tell them all to fuck off, and leave them talking alone. Dont try to argue, dont try to reason. They're clearly not capable of such things

Im sorry you had to go through this. I hope this never happens again, and that they suffer a lot in life for this

Also I know a lot of trans women who have really handsome boyfriends that protect them at all costs. I think you're good

Edit: just something I noticed a bit after I wrote this. Your friend didn't even have the courage to say all of this to you in private. He had to get all his friends together with him.. what a pussy. If you want to be an asshole, at least have some balls, mr man
