In the wake of the recent massacre at Marjory Stoneman Douglas High School, the right to bear arms and what to do about gun regulation is again under hot debate. Host Alejandro Alonso Galva speaks with historian Roxanne Dunbar-Ortiz, who says that the key to understanding the purpose of the Second Amendment is understanding white gun culture and white nationalism in our country’s history. She’s the author of the recent book Loaded: A Disarming History of the Second Amendment.
