I never actually said that was the best response to bullying, just one possible response. It's what worked for me, and I think it can work for others as well. Sometimes breaking a bully's nose will make them leave you alone, sometimes it will just escalate the problem.

I think it's unwise to universally swear off any tactic when dealing with an oppressive situation, from simple bullying to an authoritarian government. You have to determine on a situational basis which tactics are going to be most effective, and then follow through with them.
