Dale McGowan is the author of a number of excellent books about atheism. His books Parenting Beyond Belief and Raising Freethinkers are all about bringing up children without religion. He’s the author of Atheism for Dummies, a book that surprisingly didn’t exist until 2013. He began Foundation Beyond Belief to encourage atheists to give to charity. He’s the manager of the Atheist Channel on Patheos.com (full disclosure: that’s where I blog). And his latest book, In Faith and In Doubt, is all about relationships between atheists and believers.

We spoke with Dale about how to make mixed-faith marriages work, the biggest surprise he uncovered during his search, and the importance of a hand squeeze between loved ones.
