the anti-political correctness types are really just trying to enforce their own standards of acceptable discourse and are furious at their inability to do so

Their cruelty made them feel good, it made them feel proud, it made them feel happy. And it made them feel closer to one another…Their shared laughter at the suffering of others is an adhesive that binds them to one another, and to Trump. (p 101)

The critical race theory scare is a reaction to the re-evaluation of history sparked during the Obama presidency and the Ferguson protests. They sparked an inquiry into how we have a Black president but still have glaring racial inequalities that have not been resolved. That process was accelerated by the election of Donald Trump because he was so overtly running on the politics of white identity, and then it culminated in the George Floyd protests. That recognition frightened conservatives because the knowledge that racial disparities were caused through public policy, that implies the state should step in and fix it. If you are conservative and you believe that these inequalities are actually the result of in-born natural ability then you don’t want the state to do that. So I think there’s a recognition on their part that this re-evaluation of history would cause people to understand the lingering effects of racism in American life, and to prevent that, they want to make it difficult to teach history that includes the extent that discriminatory policies shaped racial disparities in America.
