We recap the diverse international conference, “Days of Atheism” held in Poland in March, including the commemoration of the 330th anniversary of the execution of Polish writer Kazimierz Lyszczynski for atheism. In honor of Daniel C. Dennett, who visited FFRF’s office last week, we play Irving Berlin’s rousing 1922 song, “Pack of Your Sins and Go to the Devil." Then we talk with author, professor and clinical psychiatrist Hector A. Garcia about his new book Sex, Power, and Partisanship: How Evolutionary Science Makes Sense of Our Political Divide.
