“Too far a retreat from reality is insanity.”

The Ballot or the Bullet (1964), Speech in Cleveland, Ohio (April 3, 1964)
Context: I don’t mean go out and get violent; but at the same time you should never be nonviolent unless you run into some nonviolence. I’m nonviolent with those who are nonviolent with me. But when you drop that violence on me, then you’ve made me go insane, and I’m not responsible for what I do. And that’s the way every Negro should get. Any time you know you’re within the law, within your legal rights, within your moral rights, in accord with justice, then die for what you believe in. But don’t die alone. Let your dying be reciprocal. This is what is meant by equality. What’s good for the goose is good for the gander.
