Some transvestites say they're living "their truth" because that way, it magically becomes the "truth"; and not a delusional, fetishized sex fantasy story they're telling themselves about a boy who was either raised to just be a colossal sissy or so emasculated by childhood anal rape he feels he must actually be a girl because no boy could possibly be so feminized.

In other words IMHO there are some cross dressers (and homosexuals) who are child sex abuse victims, and acting out this way is the result. Some of them may not be the same as the bearded and balding, self-righteous, violent narcissists in thrift-store sun dresses, demanding in a gruff, gravelly voice that you call them "MA'AM" and "SHE" or else they'll rip you a new asshole.
