They're fed a narrative and have little to no critical thinking skills.
An objective person can say there's some racism in this country, there always has been, and always will be. SJW's see racism behind every bush and rock. Their commie grifter masters use them and they're too dumb and blind to see it.
They see it. They just want the free sh*t. The problem is guilty white leftards who can't explain why the state institutions they run are so racist. Like the Princeton president that proclaimed that Princeton was a hot bed of white institutional racism and then had a fit when it looked like the DOJ was going to investigate them. White leftards love to virtue signal and their herd instincts run deep. The Slobberer jumped all over the BLM narrative until actually asked for some racist white institutional behavior and then he mentally collapsed while trying to explain one of his core beliefs.
