My parents and every single teacher i had as a kid always taught me the same thing; if you ignore bullies they will get bored ans leave you along due to your lack of reaction. The more you react, the more you're feeding the troll, so to speak. Of course, there is a limit to how much you should take but it's just a rule of thumb.
I reckon being picked on a little as kid helped me become a stronger person as i grew up. If i had a chance to visit all those that bullied and pick on me for being the little Asian kid, i'd rock up to their trailer parks, thank them for helping me become who i am today, and then offer to give them a lift to the nearest centrelink.
