Ayn Rand had CRT pegged over 50 years ago.

Racism, as a collectivist pursuit, was anathema to her strictly individualistic Objectivism. To her, all forms of collectivism be they socialism, fascism, or racism were immoral on the basis that collectivism on the national level, ultimately and inevitably leads to authoritarianism and the trampling of individual rights by the government. Racism therefore, would necessitate that same authoritarian brand of government that all other forms of collectivism required in order to sustain itself on a national level.
