I can relate to Dorothy, except I went the other way.
I was a total preppy girl for a while. Make up, push up bra, hair done, tight jeans the works. I thought being more feminine would make me feel more feminine. I tried to avoid the idea that I was a guy. But I could only shove it off for so long... I realized that I am most passionate and wonderful when I am myself. That is in the masculine role, when I can just dance and sing and nobody can tell me otherwise. When I was being the gender I wasn't, I felt weak and alienated. I'm sure Dorothy struggled with this, felt powerless as a man, and that's why she beefed up so much.
So I don't think Dorothy is any less of a woman at all. She just struggled. She had that same struggle I did. She may have thought that staying "natural" was better. But you know, I've realized that the gift of science can be a wonderful thing. Let's hope there isn't some world war that deprives us of that magnificent resource.
If it was proven that GID was not biological, I'd be pretty upset. Why? Because then they'd try to force me to be a girl. Because they'd want to use "behavioral therapy." But over hundreds and maybe even thousands of years, that hasn't worked. Transition has been the answer because it works. If GID being completely psychological doesn't take away my transition, then I don't give a damn. The problem is when the nature of the diagnosis compromises the treatment.
To be honest, I think being transgendered is partially a blessing. I have no transpride, but I will say that if it wasn't for this, I wouldn't br a man. I'd be in the other role, blissfully ignorant. Wouldn't life be a bore without this struggle, this transformation? I wouldn't give a thing in the world to be "reborn" male because I cherish this life.
