^ You mean, sex (physical) and gender (mentally) are not the same thing. I know that (though I disagree that gender has nothing to do with personality, since gender traits are a part of your personality).
What I don't get is the difference between genderqueer, bigender, trigender, pangender, nongendered, genderless, agender, neutrois, genderfluid, third gender, etc. Like, what? What the hell is the point of so many labels? And most of them are just "I was born as X, but I don't really act like it", which I think is stupid, because it implies that there is a typical way each gender should behave and that everyone who doesn't fit the stereotype isn't a real boy/girl.
I know there are certain cases where people legitimately feel like they have been born with the wrong body, and in that case, I can understand wanting a change. But when someone says "I'm female, but I identify as gender fluid", what I hear is "I'm a girl, but I don't act like it all of the time", and what I think is "So what? Not liking girly things (or whatever) doesn't make you any less of a girl. Every girl is different. Why would you even need to invent a special gender for that?" I hope I don't offend anyone with his, but it's just how I feel about the extensive pigeonholing that seems to be going on in the gender community these days.
