Yeah, the Right complains about cancel culture while also trying to cancel any book or curriculum that accurately describes the history of racism in America. They are well-practiced at suppressing school materials that make them uncomfortable, and they've been doing it for decades. (And no, I'm not talking about Critical Race Theory; they have been suppressing even the most basic topics around race for a long time).

Edit: I suppose it's different on college campuses vs. grade school. I do think college campuses are culturally and intellectually dominated by the modern Left, but it's rare that anyone actually gets fired for disagreeing. Jordan Peterson is probably the most famous right wing crank of a professor, and he still has a job. But perhaps other people have other examples.
