I believe in reincarnation, but I've never thought of transsexualism as being something that needs to be "cured"; it's just another one of the things about me that makes me different from other people. In a way, it could even be better than simply being born as a cis-guy (or cis-girl, if you're MtF), as the entire experience of being trans really lets you see things from all sides of the gender spectrum. By being socialized as the opposite gender of your own perception of yourself, and then later experiencing the social norms, etc., of living as the gender you identify as, you can understand a lot more of how cisgender people feel about their own gender roles. What I'm trying to say is, with all of this, is it even possible for a trans-person to be a close-minded bigot? xD
So, as difficult as it is to be trans in this mostly-unaccepting world, I think it's actually a gift. Even if there is a "cure", I don't want it. I am the way I am, and I'm totally fine with it. We, as a community, don't need cures, we just need complete self-acceptance.
