So you would rather me call you a stupid asswipe, versus a fucking faggot. Not much of a difference to me.
Being in an argument and calling the other person a fucktard, as hika said earlier, might not "change" them. But I have experienced the situation, and i do feel like an idiot when everybody calls me out and piles on the shit. To me, it's more effective than being all polite and proper. That's why I do it to kids all day at school.
