It's interesting how the post-op transexual comes completely full circle. A Crossdresser, (and many transexuals start off here before they realize who they are) often hides in the closet as a safety net, and lives in secrecy and often bashes gays and won't hesitate to bash another crossdresser so they can be seen as a "man". A post-op transexual hides behind their surgically altered body and then rejects crossdressers, and calls them perverts, and tries to blend in with women. It's ironic though, that society as a whole would call them the same thing. The disdain shown by some here is pathetic, and no matter how much you call it truth, it's nothing more than bigotry and hate.
The umbrella term isn't going anywhere whether it's rejected by the community or not. It's there for psychiatric reasons. We all have a "disorder" (granted I dislike the term) but that's what the psychiatric community calls it. It's there as an umbrella of all people that don't fit that wonderful binary gender system our society embraces. (It's worth noting most societies in history recognized a third gender) So whether you embrace it, reject it, accept it, doesn't really matter. Society labels us, we don't.
On a final note, before I leave this thread in distaste. I don't know what part of the transition turns you into a nasty person, but I'm thankful I don't have to go through it (at least not yet). I have no desire to become a bitter hateful person. So feel special all you want, and try to remember. You are NOT special, and a big chunk of society will happily kill you for being a "pervert" whether you have a penis or not.
Edit: I shouldn't generalize. It isn't "ALL" transexuals.
