I think Dr. Sowell explained how affirmative action has led to the propagation of BS like “critical race theory.” It is nothing more than a response by those who are out of their depth in academia to justify their continued presence.
In academia, black emphasis leads to heretofore unexplored critical subjects for theses like “Africa as the Cradle of World Scientific Advancement.” And other such drivel. It is actually funny to see what indicators these academic pretenders have the audacity to use as evidence. An example would be “Yes, African Urban Cities were centers of the Arts, Sciences and Culture.” Deep, deep down in the references, if there are any, is a cite to a stick drawing somewhere in mother Africa etched in a dried wadi-bed depicting a goat.
