The tragedy is that that country might have been the United States.
During the sixties, the MLK approach was gaining major ground, and as racial animosity dissipated in the glow of the general prosperity, the Left went ballistic.
Racial divide was to be the primary tool of the Left in crippling America, and here this damn King was making black people and white people become friends... which is why the left, not the right, hired a flunkie to assassinate Martin Luther King and blame it on "White America."
It was only after that the Black separatists and other antagonists gained the upper hand and set the black community back about fifty years.
You’ve got it exactly right and I’ve pointed the same thing out many times. It was the New Left red diaper babies who stirred up racial hatred in the 60s and 70s to make sure their Marxist divide-and conquer strategy wasn’t derailed by racial healing. Blacks have been systematically radicalized by the Left with the single aim of politically destabilizing American culture. Every time things show signs of improving the usual bunch of (mostly) white radicals shows up to pick the scabs off old wounds.
