Last time I was there the majority of the picnickers were people of color.
Your point is noted about the statues. I tend to agree about keeping. Those museums should cover these leaders and explain their excellence as military tacticians and leaders. They should discuss why and when the monuments were created, where they were placed, and why they have moved.
I’ve been to Stone Mountain many times. Interesting observation about park goers given that Stone Mountain Georgia is nearly 75% black. The monument was funded by the KKK and nearly every party involved had ties to the organization.
German concentration camps were left intact and maintained to “never forget” the genocide that occurred. Another reason why there is interest in preservation is to have a preponderance of evidence to combat holocaust deniers, some of whom are also fighting to preserve confederate flags and statues.
Preserving the history of the holocaust is far different from erecting tributes to confederate leaders well past a civil war that divided our country. The comparison really is apples and oranges. I’ve never been to Germany but I would hazard a guess that there aren’t many statues or reliefs of Hitler, Heydrich, Himler, or any of the other architects of the holocaust.
This particular pain point is easy to fix. Low hanging fruit usually has minimal impact, and this fix won’t have a measurable impact on society. However, removing the symbols and monuments of past indiscretions is if anything, directionally correct.
My two cents...
