The source material, meaning the actual audio of the exchange that launched it all, is what I found so disturbing. He try’s to make what seems a rational point about the US having more educational disparity for black kids because of resources being derived from their local tax base. He even does so in what sounded like a kind demeanor and with first hand experience teaching in the US. There was nothing racist about it or even controversial. Seemed like the DEI instructor didn’t like being challenged and decided to make an example of him. Disturbing stuff. Maybe this is not endemic of all DEI instruction, but his peers piling on and not standing up for him for fear of also being called a racist is likely not an isolated phenomenon. I feel bad for the guy. This wasn’t cool.
