Fred Clark is a progressive evangelical Christian blogger better known as Slacktivist. He’s one of those Christians who defies all the stereotypes atheists tend to have of Christians. He’s for gay marriage, critical of church leaders, and constantly frustrated with what his “tribe” does in the name of Jesus.We spoke with Fred about why he's still working on the longest-running book review ever, what will happen to the Christian church after gay marriage becomes legal everywhere, and how Christians can change church culture from the inside.Full disclosure: Fred writes for Patheos, the same network on which you can find the Friendly Atheist blog.Learn more about your ad choices.
