I've seen many people state incorrect things about transgendered people. I have a friend who's transgendered, and it makes me upset when I see people misuse terminology when it comes to her. So, let me tell you how it goes: Background: my friend was born a male, but has always seen himself as a girl He thinks of himself as a girl, and wants to be known as a girl, but biologically he is a male. Boy/Girl are used for the gender you perceive yourself as. Male/Female are used to state what sex you were born as. EDIT: Okay, I have edited the OP, to not use Wyldfyre as an example. I saw many people use incorrect terminology when it came to his sex and gender, and wanted to clear it up. However, many people got angry by that, even though calling out users (especially when it's not in a negative way) isn't against the rules. I have changed the OP to be about my transgendered friend. Hopefully you guys forgive me for my blunder. I didn't mean to insult anyone, I just wanted people to use correct terminology. Sorry for the troubles.
