Mine are almost all from arguments and usually one of two extremes - either from people who take my side, so along the lines of "damn right", "very good" and so on , or pathetic insults by people who lose an argument to me, for example "you're dumb", "Very insensitive.", "the problems are caused by people like you. idiot.". I don't think I've ever given negative rep myself, I don't see the point.
