Mr. Rogers sued the KKK (2021)
I'd argue the five minutes of episode when Fred soaked his feet with a black man in a kiddie pool delivered a more crushing blow to the KKK than his suit did.  a lot of kids saw that, and in turn became a lot harder to indoctrinate.bigots and racists unfortunately remembered that lesson very well.  teaching lgbtq and the history of race in this country is all but forbidden in some States because it works.
