I'd heard about the Trail of Tears back in history class, but the other day I read more about the horror that was the https://en.wikipedia.org/wiki/Indian_Removal_Act . Literally ethnic cleansing and genocide of tens of thousands of Native Americans whose nations had sovereign treaties with the United States in the US South. The fact that we still have Andrew Jackson, literally a President of mass crimes against humanity, on our $20 bill is an abomination.
