Just a notion: The term "transgender" presupposes a gender binary, a concept of male and female. So the crossing part of transgender is just a crossing from one to the other, or even the journey itself between them.
But, the term transgender challenges the presupposition of a gender binary too. We prove that the notion that humans come in two flavours doesn't work. Or at least that it doesn't describe the experience of all humans.
So, in the end, the term may render itself obsolete!
I think that's kind of cool.
