In the practice of radical love, you are embracing human beings across the board, but you do give a preference - very much like Jesus - to the least of these, to the weak, to the vulnerable. That includes poor whites and poor browns, as well as the poor in black ghettos.
The American Dream is individualistic. Martin Luther King's dream was collective. The American Dream says, "I can engage in upward mobility and live the good life." King's dream was fundamentally Christian. His commitment to radical love had everything to do with his commitment to Jesus of Nazareth, and his dream had everything to do with community, with a "we" consciousness that included poor and working people around the world, not just black people.
Jesus loves a free black man.
