Another salient point that must be made: if we always depict the Nazis as inhuman monsters, as most videogames do, then people learn that true Nazism is perpetrated by those and only those. So when you hear an actual seemingly intelligent human being explaining how racism is totally cool, you automatically don't see that person as a Nazi, because he is a person and not a monster. People may not be able to understand Prolog programs, but everyone has the instinct that "A=>B <=> !B=>!A". Nazi => monster, that person is an ordinary person, so he isn't advocating for Nazism. Of course, we want then to think "that is Nazism, so the person advocating for it is a monster", but many people don't think that way. In a way it parallels the failure of the War on Drugs and the Scare Them Straight campaigns.

I wish more media would humanise the Nazis, show that those are completely ordinary people, some up for the doctrine, some against it, all caught in one completely ordinary, if slightly mentally off person's plan to make his country the greatest place on Earth for his own people. They did horrible things. They did beautiful things. They were no different than you or me.
