FYI I never said that. In fact I didn't even say the word "trans" in this thread. But since you brought it up...
Making societal gender roles rigid/binary is actually something I'm highly against. And I can only speak for myself, but I would never pressure someone to adopt a label/identity they're not sure they want. Besides, only you can know if you belong in your body or not. No one else -- not your parents, not your friends, not your society. And no, not even LGBT subcultures can.
I realize what I described is some of the "mechanics" of trans concepts, though. And I do still think it's neat more and more gender bend/TSF manga out of Japan make use of those mechanics to tell emotionally interesting stories. And it is pretty wholesome IMO if the transformation is more bringing something out than forcibly reconfiguring it. That was the only point I was making.
