Dr. King was also radical in his beliefs about violence. He learned how to successfully fight hatred and violence with the unstoppable power of nonviolence.
He once stopped an armed mob, saying: "We are not advocating violence. We want to love our enemies. I want you to love our enemies. Be good to them. This is what we live by. We must meet hate with love."
