When talking about the making of Jojo Rabbit (a must see movie, in my opinion), I remember Taika Waititi making a point out wanting to represent the colourful fashion and more lively sides of Germany under the Third Reich. War movies tend to portray Nazis as dark and dull figures with no inner life other than murdering Jews and plotting for world domination. This is probably dangerous, as we won't recognize the fascists when they're in front of us. They'll be laughing and dancing as they murder the innocent.
Similar to how we study Eichmann to learn about the banality of evil, I think pictures like this one should be in every text book. This is what evil looks like — pretty much like anything else, if you're willing to ignore the atrocities.
