QuoteI don't think that there is serious disagreement in use of the terms from a medical perspective. We get into heated discussion when we come to application in our own personal lives.
But terms and definitions evolve over time. Homosexuality used to be inscribed as a mental disorder until fairly recently, just like GID. Now, it is seen as just another variant of the human genome. Things change, society evolves.
I think that we get into heated "discussions" when someone labels themself a certain way, and then doesn't stop at that. Instead, they continue on, and try to apply their definition to everyone else, as if they were in charge of such things.
I am hoping that we will evolve as people to one day accept people as they are, instead of how we want them to be. As I've stated before, if someone wants to have surgery, fine. If not, fine too. What does it matter to me? It does not. If someone that does not want to have surgery looks and behaves like a woman, than why would I call them a man? Gender role is seperate from sexual anatomy, or so I have been taught to believe.
