Pope Benedict did reference MLK while in DC regarding King's nonviolent struggle against slavery and racism.
Today on MLK day RACIAL AND RELIGIOUS intolerance has grown to 85% of Americans harboring a hatred trope of some kind and a 35% rise in violent acts. With or without Trump the white evangelical Protestant churches are going full-throttle anti-Semitic. I will remind them that Jesus Christ was killed as a Jewish person of color agitating against the corporate dictatorship of Rome.
Even if you are an evangelical WASP I remind you that you have skin in the game and will have to choose between Proud Boys authority or Federal forces guided by the Constitution.
As America will be shaped by the changing electorate, the new minority can not rely on obstructionism or eliminating voting fairness forever.
If you feel raw about this I suggest you start learning Russian.
