If they're the type of person that's not super gross, doesn't want to chop off their dick and turn their balls into a neg hole and is a more or less a normal down to earth person (by tranny standards anyway) who just wants to live their life I'd support them. In my eyes those types are just people dealing with their brain being fucked and want to be more comfortable with themselves. I can live with that.
Especially if they're cute
But if they're the johnathon yaniv / chris chan / tranch types then they deserve to be ridiculed and shamed
