Love him or hate him, think he's helping movement atheism or harming it, if you're an atheist in America, you probably have an opinion about David Silverman, president of American Atheists. Whether he's inspiring Bill O'Reilly to say incomprehensible things about science (and becoming an internet meme in the process) or putting up billboards that disturb almost as high a percentage of atheists as Christians, Silverman demands our attention.

Listen this Sunday when Silverman joins us to talk about American Atheists' past, present, and future. And to tell us what it really feels like to sit there listening to Bill O'Reilly.
