"Critical race theory" is an intentionally ambiguous term. The Republians use it as a motte-and-bailey where they tell people they just want to ban dumb s--t by Ibram X Kendi and antiracist baby and other nonsense that nobody really wants shoved down their kids' throats, but then they actually want to ban, like, Beloved or Black History Month projects or teaching that slavery was bad.
Or when they want to ban the acknowledgment of gay people, outlaw all abortions and heavily restrict birth control but do so by talking about Drag queen story hour and about not letting kids conspire against your parents to hide that they’re gay.
