It was honestly mind blowing to learn that most white Americans legit didn’t know what the US was like in the 1900s.
That realization played a large part in me investigating how white Americans basically lied themselves into believing the US gov/white Americans made amends for their crimes towards blacks during the period called Reconstruction - in reality, most gains black Americans made after the civil war (e.g. the surge in black politicians, the ability to get educated/start schools, etc.) were immediately taken away by means of terrorism, disenfranchisement, and bs legislation.
The movie/doc Exterminate All The Brutes does a great job detailing the stories Americans used to tell about themselves and how they had to deal with savage natives/tribes and whatnot. It’s hard to watch but it really shows how we’ve all been victims of very effective propaganda. I mean, we literally recite a pledge of allegiance as children. The bs goes deep.
