You will find an audio link to a PBS broadcast concerning how gay activists were the major influence in forcing a so called scientific body to change the DSMIII.
Of course they were... no one should need to see an article to know that & so what. That's like saying "Women in Britain should not have the vote because IF YOU LOOK HERE IN THIS BOOK you'll see that the major influence in changing the law were feminist activists pre-WWI..." (even though that is arguable). Why should that matter?
I agree though on the whole that people can change their gender, but I'm sure (sure of my opinion) that it takes a huge amount of effort and nobody consciously chooses to be gay, it's a development I believe.
I'm bisexual, but then I'm not Christian so I don't even need to debate it with myself (which would be an unnecessary stress). I know there's nothing wrong with it and that's all that matters to me. Men are oft' rather good looking (politely) yes? Yes. Especially me 8) . Ya know it's true, haha.
