I have encountered academics like him throughout my career as a student and professor. They are the absolute worse, they pretend to be civil, but they are the nastiest folks you will ever encounter. I watch very carefully and run very quickly from any academic that is always talking about folks "intellectual" capacity. These are dangerous folks. They are always measuring intellectual ability by some weird scale that always includes themselves at the top or in the mix. Yet, not matter what, folks of color always end up at the bottom of their intellectual scales, not matter what they have achieved.
Watch and learn from Mr. Turley - his words are historically textbook in the rationalized racist and sexist smearing of people of color that dare to reach the heights of great white men. Tell me you don't have a sense of deja vu!
