No, don't compare being homosexual or transsexual to being part-dragon. :/
Because dragons don't exist, and there's no way you were born a dragon in a human's body, sorry.
Can you prove that? Can you prove someone is actually male in a female body (or vice versa)? Is there physical proof that someone is gay, bi, straight or otherwise? No, as it's something only that individual can know for sure. That's what makes it so difficult for some people to understand those concepts, especially if they themselves haven't felt that way before.
Regardless, my point stands. Bullying and hate take on many forms, and all of it needs to be acknowledged as a whole rather than placing one of the larger problems higher than the others. Whether it's racism, sexism, homophobia, or even something that currently lacks a label, hate as a whole needs to be stopped. As I said in my other post, I feel the original announcement should have been written in a way that does acknowledge all aspects instead of putting homophobia out front.
