"In my capacity as bishop of the church I shall continue to disseminate the fable of our religion; but in my private capacity I shall remain a philosopher to the end" Synesius. It is the best arguement for free speech. When security and life is threatened by one speaking their own thoughts, you don't know what people really think. Where people can speak their thoughts outloud whether to be used for good or criticized without harm, we grow closer and we evolve.
