At the height of the coronavirus pandemic lockdowns, veteran journalist Ted Koppel was working out on the treadmill when he came across an episode of “The Andy Griffith Show” — it caught his attention because of something he heard earlier that day while listening to WMAL, a Virginia-based conservative talk radio station. A listener had called in to explain that they used to live in the Washington area, but couldn’t stand how “woke” it had become, so they fled to the South. They said something along the lines of, “We moved down here to the Carolinas, and boy, life is just wonderful. People are so lovely. They’re so neighborly. Everything is so nice.”
