Are you just being stupid yourself, or have you not seen the mass swarm of "Hi guys, i'm a girl!" alt accounts that end up being discovered as fake?
I don't see why people should give a flying forget if someone's a girl or not. Sure, they lied, but when someone lies about being a girl on this forum everybody flips out, why?
When someone lies about something that's probably more serious than that, everyone's like "o u :3" (not literally, of course, but they shrug it off like it was nothing). Sure there's been some cases (I can't list them from the top of my head) where someone's lied about something and they get a bad rep for telling that lie.
Some of these points are probably flawed, and I might have contradicted myself a few times, I'm kind of too lazy to go back and check. I'm kind of speaking from the tip of my tongue here, but the point is: They lied, so what? Should we all be dissapointed?
