The key point, as you suggest, is that this man was a collaborator not a resistor. He went along with the DEI ideology for years, until it finally turned on him in the form of the thuggish Ojo-Thompson. You have to confront this ludicrous ideology early and call it out for what it is, not wait until it's too late.

On this topic, I recommend a book called 'Whiteness: the Original Sin' by Jim Goad. It's highly entertaining and intelligent.
