The democratic platform, nationally, has mistaken pushing/promiting ID politics as policy, (of which CRT is one subset) for critical thinking or improving economic conditions for people regardless of their race, sex, or nationality.
It was a hallmark policy of Biden's administration to create discriminatory policies that did nothing to help working-class voters, and largely benefited well-off minorities and women from the upper 5-10% of the economic spectrum. Because that's who promotes ID politics... a small group of well-off people who are totally disconnected from the average non-college going American.
