Apparently (can't be bothered to fact check this) the nazis liked having parades in the dark because it was easier to propagate the idea of the nazi ubermensch when you couldn't see that the dedicated members of the nazi party were generally on the uglier side of average. As you'd expect of dissatisfied radicals, really. Probably same reason there's a stereotype of right-wing people on social media having a profile picture of themselves in a car with sunglasses on.

Anyway, as stupid as this is, Americans are generally literate, with access to unadulterated messages from the other side of the world. Imagine how stupid things were when 95% were illiterate and all information passed through a giant game of telephone before it arrived to you.
