Time to broaden the mind, people. There's one thing that people have in common, and that's that they are all DIFFERENT - sorta like the only constant is change, y'know? Just because someone is different doesn't mean that he or she is 'defective' or has a 'mental disorder'. I am a strong Christian...but I also know that if the old saw, "God made Adam and Eve, not Adam and Steve" was really in accordance to His will, He would never have allowed naturally-born hermaphrodites to be born. I've heard the counter-argument that natural hermaphrodites are so incredibly rare that it doesn't make any difference, but my point is that if God allowed even one hermaphrodite to be naturally born, then it cannot be just "Adam and Eve".
We've all got things we'd like to change. Personally, I've got a moderate case of face blindness - and it sucks, and can be really, truly embarrassing. It can't be fixed at all, apparently. But at least with transgenderism, something CAN be done, so why not do something about it?
