Preserving things like the concentration camps, Hitler's Eagle's Nest are not honouring that dreadful part of history it is a reminder to us of the horrors one person can inflict on a nation. I just posted on another thread that history is history good or bad we should not try to sweep under the rug what happened. Destroying statues who were a part of the history of this country and who, until now, have been just that a part of history is utterly ridiculous. When people look at these statues they can form their own opinion as to the character of the person but we can't/should not try to wipe out those part of history that may offend someone.
As Trump said where does it stop, George Washington was a slave owner but he was a very important part of this country should all reference to him be obliterated because it offends certain people?
