Voltaire's comment--"I disapprove of what you say, but I will defend to the death your right to say it"--is frequently quoted by defenders of free speech. Yet it is rare to find someone prepared to defend all freedom of speech, especially if the views expressed are obnoxious or obviously false. So where do we draw the line?
