Every philosopher, prophet, scientist and great political and social reformer of their day has started as a heretic. Mohammad blasphemed against the polytheist social order of Mecca, Jesus against the monotheistic legalese of the Temple, and Moses before them against the idols of the Children of Israel. The right to heresy, to blasphemy, and to speak against prevalent dogma is as sacred and divine as any act of prayer. If our hard earned liberty, our desire to be irreverent of the old and to question the new, can be reduced to one, basic and indispensable right: it must be the right to free speech. Our freedom to speak represents our freedom to think, our freedom to think our ability to create, innovate and progress. You cannot kill an idea, but you can certainly kill a person for expressing it. For if liberty means anything at all, it is the right to express oneself without being killed for it.
