Don't confuse non-resistance with non-violent resistance.

MALCOLM X: You don't have to criticize Reverend Martin Luther King. His actions criticize him. Any Negro who teaches other Negroes to turn the other cheek is disarming that Negro. Any Negro who teaches Negroes to turn the other cheek in the face of attack is disarming that Negro of his God-given right, of his moral right, of his natural right, of his intelligent right to defend himself. Everything in nature can defend itself, and is right in defending itself except the American Negro. And men like King -- their job is to go among Negroes and teach Negroes "Don't fight back." He doesn't tell them, "Don't fight each other." "Don't fight the white man" is what he's saying in essence, because the followers of Martin Luther King will cut each other from head to foot, but they will not do anything to defend themselves against the attacks of the white man.

MARTIN LUTHER KING, JR: Non-violent direct action is a method of acting to rectify a social situation that is unjust and it involves in engaging in a practical technique that nullifies the use of violence or calls for non-violence at every point. That is, you don't use physical violence against the opponent. Now, the love ethic is another dimension which goes into the realm of accepting non-violence as a way of life. There are many people who will accept non-violence as the most practical technique to be used in a social situation, but they would not go to the point of seeing the necessity of accepting non-violence as a way of life. Now, I accept both. I think that non-violent resistance is the most potent weapon available to oppressed people in their struggle for freedom and human dignity. It has a way of disarming the opponent. It exposes his moral defenses. It weakens his morale and at the same time it works on his conscience. He just doesn't know how to handle it and I have seen this over and over again in our struggle in the South.
