This is a Tweet from PragerU, December 21st 2020.
Inside is an compilation of alleged facts that are presented in a sort of argument for not removing the statues of Robert E. Lee. One of the things presented were as follows:
"Lee led U.S Marines to crush the attempted slave rebellion by radical abolitionist John Brown in October 1859."
This was framed as a reason why we shouldn't take down the statue by the way. They try to justify the argument a little later on after trying to give some background on the issue itself, the defense is.. well:
"considered it a 'a greater evil to the white man than to the black race' since 'blacks are immeasurably better off here than in Africa.'"
This is a Nazi tier argument... and is very much a pro-slavery position on PragerU's part. This channel is legitimately harmful, Free Speech is one thing, but this kind of rhetoric? It is what slave owners use to employ to A) Make themselves feel better, but also B) Justify it to other people.
