Hhmmm....I've been away from the scene for quite a long time, but I'm assuming that the expression "transgender" remains an umbrella term which can/does take in a lot of territory, so much so that I'm inclined to think it's usage can be quite confusing to a lot of folks. I'm equally inclined to think that if one means transsexual/intersex/->-bleeped-<-/et.al then one could express themselves with the appropriate term, rather than burdening the recipient(s) with a much more vague term whose precise meaning must be teased out. I'm inclined to think that not everyone loves a mystery, good or not.
If it's necessary for me to use a self-descriptor, I prefer the term transsexual (preceded with the adjective "post-operative").
