After all the discussion, there seemed to be a consensus that while most women would rather not see a penis in women's space, the key differentiator was experience. If the choice was between someone who has lived as a woman for twenty years with a penis, and someone who went to Thailand and had surgery in a matter of weeks, the one with the experience would be more a woman. For me, anyway, I'll stick with the feminists on this one. We are born the way we are born, but we make of that what we can based on the interaction of our wild dreams and the social pressure of taming. I believe that the key challenge we face is changing our mind, seeing our role and our world in a new way.
Biology determines our sex, how are born into the world.
