In such situations, of course, people don't nurse their anger silently, they moan aloud; but these are not frank, straightforward moans, there is a kind of cunning malice in them, and that's the whole point. Those very moans express the sufferer's delectation; if he did not enjoy his moans, he wouldn't be moaning.
I think there is a risk that the Holocaust will be placed under a glass bubble just like the Napoleonic Wars or the Thirty Years' War. If you don't make the connection between memories of past atrocities and the present, there isn't any point to it. There are plenty of horrible things happening today in Germany and in the rest of the world.
