Nobody in this thread is going to watch those lectures.
They should. But they won't, because their minds are already welded shut like a bear trap.
I'd also recommend everyone read
The New Jim Crow: Mass Incarceration in the Age of Colorblindness. It'll challenge everything you think you know about modern incarnations of racism in America, and is particularly relevant to this thread.

But again, nobody will read this because anyone who attempts to take a critical look at the history and current state of race relations in the US is just a "whitey-hating racist grudge-monger."
