Do you believe in teaching your kids how to defend themselves?

The bullying question made me wonder about this. When I was young my uncle taught me how to throw a mean snapping left jab and a right cross. He also taught me to go for the nose. No one messed with me more than once. Do you think teaching your kids how to handle bullies would help them deal with this? I’m very non-violent now, but I’m thinking the ability to handle confrontations helped me throughout my childhood. It wasn’t the best way to handle things, but sometimes the bullies need their asses kicked. Your thoughts? And I hear the P/C cries already.:)
