Bayard Rustin's Vision is Why Bigots Use Dog Whistles
Bayard Rustin was an American civil rights icon. He was the main organiser of the March on Washington for Jobs and Freedom. He also influenced Dr. Martin Luther King Jr to use non-violence as a tactic in the fight for civil rights. He said:
" Our job is not to get those people who dislike us to love us. Nor was our aim in the civil rights movement to get prejudiced white people to love us. Our aim was to try to create the kind of America, legislatively, morally, and psychologically, such that even though some whites continued to hate us, they could not openly manifest that hate."
Bayard Rustin; From Montgomery to Stonewall (1986)
This has come to pass, people can't openly manifest their hatred in public. That doesn't mean that hatred and bigotry go away. Bigots have found other means to inject their bigotry into society. Social conservatives do this frequently. They will talk about the "traditional family" being under attack, or that the transgender agenda is destroying society.
When Seth Andrews tries making the point that Nazis don't exist (because the National Socialist German Workers' Party/Hitler was defeated in 1945), Thomas Smith tries to claim that New Atheists haven't merged with right-wing conservatives, or Sam Harris claims that white supremacists have no cultural influence/that they're the fringe of the fringe, they are being destructively pedantic.
