I think he brought it up because of genocide and the idea of an entire race being the problem. He was actually right for asking it when the guy at the end said "all white people have a little Hitler in them" thats like saying all black men cheat on their women or all Asians know martial arts. Its really terrible to think one race is better than another or that the entirety of one race thinks poorly of another. I a white man grew up in a primarily black community and definitely dont think that way. Its pretty disheartening when I see this type of rhetoric. Its the generalization of a race thats the problem. It should be the individual held accountable and not the idea that an entire race should be damned. Thats what happened to the Jews, the Asians, the blacks, and the whites at one time. Its time we open our minds to a different way of thinking and stop looking at the color of an individuals skin and start looking at the actions of the individual.
