You realize, of course, that the usual “alternative explanation” offered up is simply that black people really are intellectually inferior and naturally prone to criminality and moral bankruptcy. And the people who make that argument point to all the same statistics about arrests and academic achievement and career success that the CRT people use as their “proof”.
It’s not a very nice (or accurate or scientifically rigorous) argument, but it’s the one they’ve got and they seem to like it.
