That was in 1948, three years after the discovery of Auschwitz, Buchenwald, et al., when tolerance seemed like an important concept to instill in kids. Three years later, for the “Adventures of Superman” TV series, and amid various McCarthy and HUAC hearings in which people lost careers and lives because of left-wing political leanings, “tolerance” was removed in favor the all-purpose “American way.”
