Lefty-trendy academics are always inventing new forms of babble that are transiently fashionable and then disappear up their own fundament. The big noise about CRT is merely because the far-right Republican Party sees it as a useful talking-point they can misuse to appeal to the great bulk of their voters who are fat, ignorant, foolish people who are also very often racist without even realizing it. And clearly the USA remains a highly racist society in which every part of the system discriminates against people whose skins are darker than the oddly-colored orange cretin Trump.
