On The Posner Show, E.J. and Maggie debate gay marriage. Maggie argues that sex can't be separated from reproduction. E.J. believes gay marriage is the result of changing attitudes toward marriage in general, not a cause of that change. What is the purpose of civil marriage, and is it compatible with gay marriage? Maggie explains why she thinks gay marriage could negatively affect marriage as an institution. Finally, they discuss whether children need a mother and a father.
