The new documentary “Love Wins Over Hate” features a series of honest and thought-provoking interviews with former white supremacists, and others who held extreme views but have since renounced them. It attempts to get to the heart of why people hate, and sometimes take on extremist ideologies like white supremacy. And what it takes to escape that world, and in some cases go on to work to help others escape. We talk with its producer and director, Susan Polis Schutz.
