Never Forget indeed. But also never forget the other state-sponsored mass murders of the 20th century, at least two of which were far greater in number than the Holocaust. None of that diminishes what happened in Germany, but it does put it in the context of a larger question about why so much blood was spilled in the last century by ideologically-motivated governments against their own citizens in peacetime.
Universal Holocaust education is critical to ensure that not only do we never forget, but that our children and grandchildren fully comprehend the depth of the greatest crime in history, so nothing like it ever happens again.
To call the Holocaust the "greatest crime in history" is to do real damage to the memories of the 10 million or more (maybe 20) killed by the Soviets and the 30 million or more under Mao. That they came from self-proclaimed communists/socialists doesn't change a thing. In fact, it should force us to look more carefully about what happened in Germany and why and, again, to recognize both the unique elements of those events but also the commonalities it shared with those regimes who killed more and those (like Pol Pot) who killed fewer. What was it about the ideas that rose to popularity in the 20th century that opened the gates to the systematic murder of tens of millions of innocents?
Isolating the Holocaust in ways that treat it ONLY as a singular event is the worst way to go about Holocaust education. Yes, teach what happened, but place it in the larger context of the river of innocent blood that defined the 20th century.
