Something that seems strange to me is how Americans refuse to teach that sl4v3ry was something that existed and was in their country.
type... one of my first memories of my childhood (at 4-5?) is watching the first episode of an educational series from my country(the one in the images, I looked for it to show it ).
The formula was simple, our protagonist travels in time and falls on an important historical date, in this case 1810.
In the first 15 minutes of the first chapter we are introduced to the character Nina, And she explains to us that being the daughter of a slave and a free bl4ck woman, she is also free (as shown in the pictures). Nina becomes an important character as she is the companion who explains most things to the protagonist and accompanies him in most chapters.
I didn't think about it much at the time and my 5-years-old mind just said "there was a time in history where you could buy pe0ple" and that was it.
Now that I see the American disaster of teaching this in schools I just say, "Isn't that what learning is supposed to be for? to prevent it from happening again?"
(PS to avoid any comments disasters: Yes, the series condemns these acts. )
