All of the videos were powerful, and a good review of much that I knew. But some facts stood out that I learned for the first time. In the video on racism in medicine, it reported on a relatively recent survey of medical students, 25% of whom thought black skin was thicker, and Black people felt less pain. Also, the history of racist dehumanization of Mexicans at the boarder explained a lot about current ICE detention and abuse. It's not new, it's a continuation of white control over "non-white" peoples that means whites can continue to benefit.
