David Smalley is a former Christian musician who became an atheist after studying psychology, sociology, world religions, and his own faith. He soon turned into a secular activist.

He was the editor-in-chief of Secular World and American Atheist magazines, the author of Baptized Atheist, and co-founder of AtheistAudiobooks.com. His Secular Media Group will soon release a children's book titled Tiny Thinkers: Charlie and the Tortoise.

You may know him best, however, from his incredibly popular podcast Dogma Debate which has tens of thousands of weekly subscribers.

We spoke with David about why it's so important not to be an angry atheist (if you can help it), what it takes to be a successful podcaster, and why he's so passionate about atheist activism.
