I don't understand the context of this, but as someone with a sexual development disorder, fuck that guy for trying to insist there's more than two sexes. He's indirectly calling people like me "others" or some kind of alien sexless beings, which is extremely disrespectful and ignorant. I still have a dick, I'm still a guy, the fact that my hormones and/or chromosomes might be fucked up doesn't make me any less so.
