Also, it's not 6 states banning CRT, it's 20 states now.
(CRT is calling white children oppressors, and black children victims. Neither is accurate or helpful. CRT is derived from Marxist Critical Theory. Since the US doesn't have a class struggle, racism has been inserted to make it a racism struggle.)
Perhaps a more accurate way to frame this is that both CRT and Marxism are separate instances of a collectivist way of thinking that tries to categorize people into groups based on their perceived power, where what informs that categorization is low dimensional (e.g merely class or merely race+gender). In that sense they're similar ideologies.
This is just incorrect. Critical Theory is a product of the Frankfurt School. They were explicitly applying Marxist thought to twentieth century politics, and wanted to understand why Marxism wasn't successful in the west.
This is a basic matter of record, not some wing-nut attempt to slander. Critical Theory is reworked Marxism to try to apply it to the modern West.
