People are complicated and you really can't judge what people do at different times in history. If we look at our world today we see so many different opinions about public figures and we don't know them or any of the circumstances surrounding whatever event people are writing about.
I personally think it's ridiculous to start tearing down statues, outlawing books that were considered classics, renaming schools. Where does it stop? Is it really worth it? We don't know the facts. If you watch a movie from the 70's you often see how politically incorrect it is with today's social justice warrior standards.
People are acting like an out of control immune system.
