Nonviolence is a powerful as well as a just weapon. If you confront a man who has long been cruelly misusing you, and say, "Punish me, if you will; I do not deserve it, but I will accept it, so that the world will know I am right and you are wrong," then you wield a powerful and a just weapon. This man, your oppressor, is automatically morally defeated, and if he has any conscience, he is ashamed.
