R. Marie Griffith, the John C. Danforth Distinguished Professor in the Humanities at Washington University in St. Louis, discusses her book, Moral Combat: How Sex Divided American Christians and Fractured American Politics. She gives a history of how the Christian consensus on sex unraveled, and how this unraveling has made our political battles over sex so divisive.  This is a rebroadcast of a segment guest hosted by Mary Harris.
