I agree that people should absolutely be looked at from all angles. However, I also understand that we shouldn’t honor people who traded slaves, or killed natives, or fought to keep people enslaved.
Its important to remember that even history is political. A lot of us were taught the version of history the state wanted us to know, but they often leave out the parts that make them look bad. “History is written by the victors.” Slaves, natives, and refugees are often overlooked in history because people want to forget the “bad times.”
