That video was a repudiation of the 1619 project. It does not deny that slavery happened or that racism exists. America's beginnings, just like any historical event, can get viewed through many different lenses. The 1619 project aims to indoctrinate children with harmful critical race theory brainwashing. CRT aims to train children to be racist against whites and call them oppressors. It teaches black children to see themselves as permanent victims and robs them of their agency. What we're talking about here is highly sophisticated and weaponized propaganda meant to cause maximum harm, not only to students but to society, writ large. If CRT's aims get met, America will move towards the path of apartheid, rabid tribalism, collectivism, and possibly a race war. CRT is a wolf in sheep's clothing and probably brought to you, in part, by the likes of the Fabian Society and similar organizations.
