Nazis are just purveyors of an extremely well defined version of the “Us and Them” mentality that evolved with humanity as a way of conserving resources within a tribe. Talk about the folic acid science behind skin color with them, it may blow their views to pieces…or not. It’s time that we see humanity as one tribe and earth as our first home. Care for your fellow tribes people, and care for our first home. Cast dissent on those who care selectively based on morphology.
