It's a little late for me to sound off on this whole discussion, but it's been my perception that while most men tend to simply not accept us at all. Like women, the ones that do accept us, accept that we FEEL that we're SUPPOSED to be women, not that we ARE women.
They don't accept us as women period. The only people that seriously accept us as women are the ones that don't know we're trans. If anyone says differently, i'd never believe them.
