Freedom of expression must be considered sacred and thought can only be corrected by counter thought. A people which is able to say everything becomes able to do everything. If liberty means anything at all, it means the right to tell people what they do not want to hear. If that is granted, all else follows. Free speech is the whole thing, the whole ball game.
Free speech is life itself.
Without the freedom to offend, it ceases to exist. The greatest threat to freedom is the absence of criticism. The essential support and encouragement comes from within, arising out of the mad notion that your society needs to know what only you can tell it. I may disagree with what you have to say, but I shall defend, to the death, your right to say it. We have a natural right to make use of our pens as of our tongue, at our peril, risk and hazard.
