[Prudence]

I've known a number of transgendered people of all types - MTF, FTM, surgery, not surgery, considered "homosexual" after, considered "heterosexual" after. Most I couldn't have imagined in their societially proscribed gender. One I had a real struggle with, because it seemed more about being edgy and kinkier-than-thou, but I didn't know him that well and it wasn't really my business.

As for why they're all lumped in together - because to the outside world it's all the same deviant sexual behavior. The lumping together comes more from an outside view, I think, driving the various groups to combine forces. Strength in numbers, and all that. Plus, the transgendered will probably be the last of the LGBT group to be accepted. Their numbers are too few, and too few can identify with them. If gender is no longer an obstacle to marriage, jobs, housing, etc, then many of the legal hurdles the transgendered face will be addressed.
