You present well and I'm glad to hear your heartfelt views.
However, a spectrum where the bottom is crossdressers and ->-bleeped-<-s and the top is transexuals? That's not a spectrum (red isn't better than green, blue or violet, it's simply different). And what about taking my fashion tips from "real women"? Sorry, I'm every bit as much a real woman as a natal female. Of course I agree if one wants to pass then modelling natal women is the right way to go, it's just a question of language.
Your need to define who's trans and who's not again, isn't your call. Nevermind that a gay man who simply chooses to transgress gender norms is iny mind trans if that's what he chooses to call himself, ultimately it's always up to the individual, nor others to define their own identity.
I would rather say we can identify many dimensions of being transgender. Passing or not or non-binary, medically transitioning to whatever degree or not, etc, etc. Most would agree that the most essential element is whether our brain and thinking is relatively feminine or masculine, however I would always allow that if a person's circumstances, rather than biological determination makes them trans then they're simply trans to me.
