In fact, both Di'Angelo and X Kendi have written opinionated, arguably racist (reverse racist?) hot takes that both boil down to the self-flagellation of one race. The premise of both books (and yes, I have read them) is that white people are born with an original sin that cannot be cleansed, but only fought against, and the only way to do this is accept the (false) premise that you are intrinsically a racist and you must actively fight against this. By "you", I of course mean "white people". Ascribing negative traits to someone based on their race is racist, QED.

They are both textbook examples of a false premise. Extremely difficult to refute because by design it's created to immediately incriminate people opposed to it. So no one with any sense opposes, lest they become an anti-anti-racist, which somehow means "racist". It fails the freshman logic course test which tells you all you need to know.

They qualify as garbage. If not because the authors have a clear agenda other than (social) science, but because their cases are based on demonstrably false premises that lead to wild, racist, and absurd conclusions. There is very little difference between these books and the racist books of 100 years ago except the premise was altered and the colors changed. They might belong as a times best seller in today's social battlefield but there is no substance in them besides their inflammatory titles and racist conclusions.
