Nothing in the videos was news to me. I've read of all of this before. And yet, going through them all, I was particularly struck by the all-pervasive evil, the many disguises that racism takes on. Sometimes there is a starting point where "reasonable people" could make ill-founded assumptions. But then it morphs beyond those assumptions into something that is awful. So maybe the learning here is that I must always question my own assumptions, motivations, belief systems. I must turn back to seeing where I deliberately refuse to see each and every person as having the same worth as I do, and act accordingly.
