Agree.Defacing the past is unwise, they serve as reminders of our history, whether they be mistakes, right or wrong, good or evil. Who knows what modern figures might be removed from public places 100 years from now.
The problem with removing the reminders of the dark times of the past is that in 20-30 years, kids growing up will have this illusion of that we never did anything wrong. If we don't teach the kids of the things that we did wrong in the past, they're more likely to repeat our mistakes one way or another. It's through the mistakes we learn, and by remembering them, we have a better chance of not making the same ones.
