The real question is, will going around changing names on memorials, removing statues, etc actually change attitudes and by extension reduce the racism in society in general, or will it just be a load of empty gestures and things stay the same when the 24/7 media with its goldfish attention span has moved on to another subject?
If the latter then it’s all been a waste of time. For me this falls into the second category, it should be left as is as an example of the culture of its time, kept in its proper context, and used to educate people. Removing it also removes the opportunity to educate.
