I do not believe this is true in any meaningful sense. Schindler's list, Operation Valkyrie and the like are firmly embedded in popular culture. And of course the claim that all of any nation share an ideology is absurd to anyone who thinks about it for two seconds, but I'll give you a pass on that because I don't believe you're talking about people who think for two seconds (I claim that that is also an important error in your worldview, but that's tangential).
