I was en route from Greeley, Colo., to Davenport, Iowa, where Bush is about to speak, when I started reading Occidentalism by Ian Buruma and Avishai Margalit to occupy my down-time. The authors are telling the familiar story of Sayyid Qutb’s travels in America, surely one of our more ill-fated cultural exchanges. But one detail I had not noticed before: “A church dance in remote Greeley, Colorado, hardly a metropolitan place, struck him as wickedly lascivious.”
