One of the misconceptions that muddle the West’s debate over Islam and free speech is the idea that people should be totally free to insult. Free speech is never that absolute. Even — or perhaps especially — in America, where citizens are protected by the First Amendment, there are certain words and opinions that no civilized person would utter, and others that open the speaker to civil charges.
Insult? I guess they didn't read Maureen Dowd's columns about Sarah Palin last fall.
Maybe what they mean is that you should not insult Islam?
