Then and Now
From 1868 (and a 14th amendment that gave birth to black “Americans”) to 1968 (which saw the brutal murder of a black Christian preacher whose elevated voice of the oppressed was silenced), 100 years of segregationist policies and practices protected and preserved white supremacy and oppressed nonwhites.
Those policies & practices didn’t die with the reverend Dr. Martin Luther King Jr. They remain in place today, more than 50 years later, in every city in America.
