The folks at Collector's Weekly used to delete references to Nazi items from their forum, but then considered the question of why people collect such things. Not everyone who collects Nazi memorabilia is a Neo-Nazi or a Hitler fan. Some subscribe to the philosophy summed up in a George Santayana quote: "Those who cannot learn from history are doomed to repeat it." They are also aware that some find any instance of the Nazi swastika offensive.

But for collectors like Kevin Mackey, Nazi memorabilia, particularly those bearing the swastika, are unambiguous reminders of this suffering. Though upsetting to many, Mackey believes these pieces have a place in any discussion of World War II. “To obliterate the symbols of Nazi Germany,” he says, “would be to obliterate that period from our knowledge, and to forget what took place. We need to be aware of what caused Nazi Germany, what happened, and how much horror came to this world because of it.”

But you don’t have to look very far, Mackey says, to see what happens when history, however upsetting, is expunged from a culture or society. “We have a leader of Iran today who says the Holocaust did not take place. But even my youngest daughter knows better, and she’s in junior high school. So we should not remove these pieces from the public knowledge, from public view. I don’t see it as a glorification of Nazi military items. I’m a historian—these are pieces of history.”
