"How do you respond to “Islam is the solution�? or “Jesus Christ is my Lord and Savior�?? How do you converse with someone who justifies the war in Iraq—as Christopher Hitchens does—with the tautology that we have to “kill them over there so they do not kill us over here�?? Those who speak in these thought-terminating clichés banish rational discussion. Their minds are shut. They sputter and rant like a demented Othello. The paucity of public discourse in our culture, even among those deemed to be public intellectuals, is matched by the paucity of public discourse in the Arab world."
