Well one, I don't accept your premise. Statues were never meant as tools of education. They are celebrations of people. Its easy to understand this, students don't gather around statues every morning to receive instruction they go to schools and statues typically aren't placed inside classrooms but prominent public spaces.
Secondly, taking down statues isn't erasing history. History is much more resilient then you give it credit for. It exists in memory, in stories, in books, in movies, in pictures, on the internet etc. We preserve more history today than at any other previous point in time.
Third, teaching the real history, that Washington was a piece of shit slave owner is exactly why you are hearing and are going to be hearing more and more calls to stop venerating that piece of shit in our culture.
You're the one seems real triggered by this conversation. I'm fine.
Anyone's. Just not yours. Your ability for either seems broken.
