Good for you. I hate bullies. I heard this story once about my mother-in-law's tailor / dry cleaner. He'd moved to upstate NY from Italy. His kid was being physically bullied on his way home from school. One day, the guy hid in the bushes and jumped out at the bullies with a kitchen knife and told them "If you toucha my kid again, I'll fuckin kill you."

Nobody should have to put up with bullying. When it's this social kind on the Internet, I think in many ways it is worse because it's less clear how to defend yourself.
