Not mIRC!!!
I hate it when people hate on children for no good reason (see: the 12 year old boy arrested for farting thread). In fact, I hate it when people do it for ANY reason.
I hate parents who hit their children for no reason, even if it's just 3-4 slaps. Seriously, how #$%#^ up do you have to be to see that your child is accidentally tripping on some fallen leaves, to let him fall, and then slap him a little so that he doesn't fall the next time?

I'm not sure about the farting thread, since it seems we are not given all the details, but don't get me wrong, I can hate annoying little kids too. I don't like being around children <12 too much, because I just find them an annoyance after 1 minute, but their own parents hitting them for no reason pisses me off so much...
