Depends on the person. When revolution hit my countrys biggest bridge wich was named after the dictator had its name changed and even today some people that dont support the dictatorship think the name should had been kept the same.
I don't think stuff that was fine in its time of constrution should be demolished because I believe we should remember the past. Not to cherish it but to learn from it.
Another example would be auschwitz. It remains there so people can be reminded of the terrible cost of fascism.
Instead of destroying said monuments why not move them to a museum like for example what they do in the jim crow museum?
We should never erase our colective and cultural history so we don't forget the lessons of the past.
Does this make sense to you?
