Haha! This came out when I was in high school.
I cited it as part of an explanation for why whites outperformed blacks in the Olympics to one of the few black kids at my high school in the pool at P.E. one day. He and his two brothers were all fine rural athletes, not dominant ones, and did well in track. None could make the basketball teams.
He just looked at me like I was some brainless zombie who had been inculcated in snow-driven racist thought, and wasn't attempting to explain why their dominance on land didn't translate quite as well to the water. Of course, the larger reasons are cultural, but it was one of the first experiences I can recall where I could see someone
presume knowledge of my mind when it was
actually him who was entrenched in a prejudicial bias.
Ironically, this brother, the youngest, is a hardcore conservative today, and posted himself in a MAGA hat on Facebook during the campaign. At the same time, the middle brother was posting Black Israelite memes/jpegs and advocating for racial segregation out of the belief it would favor black interests. I actually engaged him when he started pimping this bizarre CT that Harlem was doing much better in the early 20th century prior to greater integration. This argument was rooted, wholesale, in an obscure statistic about how a dollar spent longer being circulated in the local black community at that time. I tried to educate him on why this wasn't a healthy metric for the overall health of a local economy, but he was unreachable. His ignorance was astounding-- unsettling, even. I had no idea. He did not strike me as a stupid young man when we were in high school.
