In the latest episode I talk with Christian Picciolini, a former neo-Nazi skinhead, who left the movement over a decade ago to devote his life to “breaking the hate” through his Free Radicals Project. In addition to being an acclaimed author and public speaker, Christian is also an Emmy-award winning producer of documentaries. Last year, he did a three-part special report series entitled “Breaking Hate” for MSNBC. Previously he published White American Youth: My Descent Into America’s Most Violent Hate Movement – And How I Got Outand this year he published Breaking Hate: Confronting the New Culture of Extremism.

My first guest is the British football writer James Montague, the award-winning author of four books, including When Friday Comes: Football, War and Revolution in the Middle East and Thirty-One Nil: On the Road With Football’s Outsiders. Having seen games in countries as far away and remote as North Korea and Yemen, James is the envy of all groundhoppers like myself. Today, we will talk about his new book, 1312: Among the Ultras, a fascinating read about the most radical elements in contemporary football. Highly recommended!
