On Freethought Radio we hear about FFRF’s Ron Reagan ad on the penultimate Jon Stewart Daily Show, a Jesus sign in an east Texas town, bible verses removed from an Arkansas city webpage, and “In God We Trust” challenged on municipal vehicles. After hearing Bo Burnham’s anti-religious rap song “Rant,” Annie Laurie Gaylor and Dan Baker talk with author, poet, and critic Katha Pollitt about her new book Pro (about abortion rights), and her previous book Learning To Drive, which has became a major motion picture released this week starring Patricia Clarkson and Ben Kingsley. Then Skeptophilia‘s Gordon Bonnet has a look at how certainty works in science and how some in the public misunderstand the uncertainty that’s baked into scientific theories to mean that scientists “don’t really know what they’re doing.” Last week we honored 19th Century orator and Freethinker Robert Ingersoll, whose birthday was last Tuesday. In the latter half of that Century Ingersoll was the face of religious skepticism and his arguments were the ones that caused people to question their faith. Today, the most prominent figure out on the front lines actively debating theists is the public speaker and internet personality, Matt Dillahunty, host of the weekly show the Atheist Experience. Bo Bennett, host of the Humanist Hour podcast interviews Dillahunty in hour two of the show and asks him how he got to where he is and what he’s learned after more than a decade of debating theists.
