It's one thing to tear down a statue of Hitler or Stalin. It's another thing to target Lincoln, or the Founding Fathers.
It's true that we don't learn history from statues. That point entirely misses the mark. The hatred directed at our historical figures, to the point that you can’t stand to see their likeness, says that you're a dense person in regard to some basic concepts.
If you think that only perfection deserves reverence, in one way, I feel sorry for you. In another way, I see a narcissism in you compounded with obvious short-sightedness.
In a blink of an eye, you and I will be the old generation. We'll be the ones who were out of touch. We will be the ones who failed to see far enough, and predict how future generations will judge us.
What's more, all of you seem to think that, if you were born a hundred or two hundred years ago you would have the same values. No, you wouldn't.
There's a valuable concept of, "A man of his time."
By today's standards, of course Lincoln was racist. So was Ghandi (much more so). Ghandi was a man of his time. Lincoln was a man ahead of his time.
William Lloyd Garrison was a man far ahead of his time. Having read William Llyod Garrison and knowing a great deal about his friendship with Frederick Douglass, I think you would have to twist the word "racist" around like an ouroboros to make that accusation; but, that is what self-proclaimed "progressives" are doing these days.
Hitler wasn't a man of his time. Stalin was never a man of his time. Mao was never a man of his time. Nero wasn't a man of his time; but, Seneca was probably ahead of his time.
Subjugation of certain people and hatred of certain people have always been common regardless of the mores -- and that definitely includes modern culture -- and it's not isolated to your political opponents.
Mass murder is another thing. Hitler wasn't Time Man of the Year because Time thought he was great. It was because Time knew what he was doing to the Jews and profiled him as the Man of the Year, because he was the most dangerous.
Most of us will be forgotten in a hundred years or so. Some of us will be a distant memory in a matter of weeks for all we know. Very few of us will make the history books in a hundred or a thousand years or more.
When people look at us in the future, we all better hope, at some level, that they will be kinder to us as their ancestors, than we have been to our ancestors. I hope that they'll be kinder to us in two-hundred years than many of us have been to our parents and grandparents.
We're only where we are now because our ancestors got us here. The only reason why the Western World is privileged enough to be debating pronoun mandates instead of whether or not it's okay for people to own other people is because our ancestors fought that out for us. The only reason why we can break the orthodoxy with such freedom in the Western World is because so many of our (however imperfect) ancestors lost their freedoms or their heads for speaking against the established order and the moral order.
Understand that, if you're really in favor of progress, your hope should be that the next generation is better than ours, and that the generation after that will be even better than them.
If our future generations achieve progress, they'll look back upon us -- you and me -- and find it hard to believe that human beings could be so vacuous, if not barbaric.
If our future generations never regain a reverence for the past, whoever you are, whatever you believe, if people even remember you, it's a safe bet that they'll spit on your grave.
