It is not just the right of the person who speaks to be heard. It is the right of everyone in an audience to listen. Every time we silence someone, we make ourselves a prisoner of our own action, in that we deny ourselves the right to hear.
Freedom of speech is meaningless, unless it protects the freedom of the person who thinks differently.
