By "critical race theory" do you mean that there's only one human race? This isn't a crackpot conspiracy; TBH, it makes the belief in multiple races look crackpot. Similarly, by "intersectionality" do you mean the advances in civil-rights law that let us recognize when women of color are being discriminated against? This isn't crackpot, but basic set theory being applied by lawyers.

Imagine being a country which doesn't feed everybody, house everybody, clothe everybody, give health care to everybody, but does have plenty of time to explain how skin color matters a whole lot and can fund police which will enforce skin-color policies. That's rightism in a nutshell.
