How is it not a mental illness?
I see so many people on these boards defending people's "need" to change genders. There are plenty of medical professionals who see it as a mental disorder.
If you are a girl and are masculine that's fine. If you're a guy that is feminine that's fine too. Why do you HAVE to be classified as the opposite sex though?
People who base their identities on whether they are a man or woman are clearly trying to escape reality. There is more to a person's character than what gender they are.
Why is so much emphasis placed on pronouns and body parts rather than the person's personality?
