While lots of people argue over the status of statues about historic figures that may have had slaves, bigoted attitudes and so forth, I have an optimistic thought about this. The controversy happens because society has progressed over the years. Attitudes and practices that would be considered bigoted today were basically normal back then. The normal is changing; at least in western societies.
The best way to deal with these statues is to keep them for remembering history. Rewrite descriptions to acknowledge the faults as well as the accomplishments of historic figures. Possibly move some of the statues to less prominent locations.
Even today, no one is perfect. To a large extent, we are all products of our times. Folks of the future might tear down statues of people from today who continued participating in the culture of fossil fuel consumption. We are a product of our times. To a large extent, people do the best they can given the norms and culture they live in. Those norms can change.
