I noticed the similarities... the Dark Mark and the swastika, Hitler and Voldemort, the Death Eaters and the Nazis. But when I was reading something not too long ago, I noticed that in WW2 Nazis came to german schools to teach children racism, to tell them about how the Aryan race is superior. Does this seem similar to DH, when the Carrows come to teach at Hogwarts, specifically when Alecto Carrow teaches Muggle studies?
