In a free society, people should have the right to criticize a religion; they should have the right to do so, and of course their criticisms are themselves open to criticism; that is the essence of freedom of speech and thought.
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.
