It's no great revelation to say that white supremacists are dumb. By definition, anyone who believes in the superiority of one race over another is not the sharpest knife in the drawer, and Michael Beach Nichols and Christopher K. Walker's often chilling documentaryWelcome to Leithtells how a particularly low-IQ group of neo-Nazis attempted to take over the tiny hamlet of Leith, N.D. In 2012, Craig Cobb — who refers to himself as "one of the most famous racists in the world" — started buying up property in the town (pop. 24), intent on turning it into an Aryan wonderland. Locals were not down with this, and took to the law to drive Cobb and his gun-toting, Sieg-Heiling acolyte Kynan Dutton out of Leith.Welcome to Leithis a frequently ugly spectacle about the limits of free speech and good taste, and not just because of clown prince Dutton's unspeakable attempt at a Hitler moustache. The historical tendency of Nazis to document their every movement again hoists them on their own dumb petard, especially in crucial footage of Cobb and Dutton "patrolling" the town by threatening the residents with shotguns (#SecondAmendmentHooray!). It's all filmed by Dutton's girlfriend, who isn't smart enough to hold her phone horizontally. White people, amirite?
