It's exactly like those people who live as vampires(no I'm not talking about our very own Vampy LOL) or live as furries or whatever.
And the thing is, most of the TS (transsexual) types really buy into the myth that there's only one way to be, that is either male or female.
Gender exists on a continum, just like almost everything else. Gender is not binary. Maybe if more TS people understood that, then they wouldn't have so many issues. I really do think many TS people don't quite understand that a lot of people have feelings that they wish they could be the other sex. It's not talked about commonly.
I think most true TS people are prolly intersex people who had surgery as little babies. I wish we could change the world so that TS people wouldn't feel the need to get surgery in the first place!
