On Friedersdorf, the conversation kicks off with Mark discussing his column on purity balls, where fathers pledge to protect the chastity of their daughters. They next talk about Mark’s profile of David Frum—are Frum’s politics a psychological reaction to his famous mother? Conor disagrees with Frum’s dismissal of libertarianism, but thinks he deserves credit for publicly changing his mind at some cost to his financial well-being. The two go on to consider what the goal of parenting is, and the thing that parents in Mark’s neighborhood fear most. They discuss the good and the bad (but mainly the good) of the sexual revolution, and Conor argues that society should stigmatize absent fathers.
