Roberta, pretty hard to stuff all of us in one box. I can't say I am transgender. Certainly have no interest in going that far. CD'ers fall into all kinds of groups, straight, sexual play, to those that desire to transition.
I am in the middle somewhere. No interest in transitioning, enjoy the "play" side of CD'ing, but still wonder if I don't have some female genetics floating around inside. I don't feel I fit into the LGBT alphabet.
As for the speaker mentioned by the OP, I find it hard for them to rigidly exclude CD'ers as some definitely fit into the LGBT somewhere. Perhaps, in her mind, at that point they are gays or queer that crossdress.
