“Beyond all the other reasons not to do it, free speech assaults always backfire: they transform bigots into martyrs.”

“My belief in free speech is so profound that I am seldom tempted to deny it to the other fellow. Nor do I make any effort to differentiate between the other fellow right and that other fellow wrong, for I am convinced that free speech is worth nothing unless it includes a full franchise to be foolish and even...malicious.”

“There is a fine line between free speech and hate speech. Free speech encourages debate whereas hate speech incites violence.”

“He that cannot reason is a fool. He that will not is a bigot. He that dare not is a slave.”

“Free speech is the whole thing, the whole ball game. Free speech is life itself.”

“Goebbels was in favor of free speech for views he liked. So was Stalin. If you’re really in favor of free speech, then you’re in favor of freedom of speech for precisely the views you despise. Otherwise, you’re not in favor of free speech.”
