A strong man must be militant as well as moderate. He must be a realist as well as an idealist. If I am to merit the trust invested in me by some of my race, I must be both of these things. This is why 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. Wherever this weapon is used in a manner that stirs a community’s, or a nation’s, anguished conscience, then the pressure of public opinion becomes an ally in your just cause.
