The idea of burying a negative event of the past is wrong anyway. A country should never be held responsible for it’s past, but history is history, and if creative talent draw from that era, it should be fair game to paint an accurate portrayal and not be swept under the rug for the present people to take shame for.
Germany will forever be known as the country that Hitler motivated to atrocities, but that’s not the case now. It’s just a bad era of history for them. Censorship is not the answer.
