Bonhoeffer once said of bystanders. “God will not hold us guiltless. Not to speak is to speak. Not to act is to act. - Isabel Wilkerson

The anthropologist Ashley Montagu was among the first to argue that race is a human invention, a social construct, not a biological one, and that in seeking to understand the divisions and disparities in the United States, we have typically fallen into the quicksand and mythology of race. “When we speak of the race problem in America,” he wrote in 1942, “what we really mean is the caste system and the problems which that caste system creates in America.

What people look like, or, rather, the race they have been assigned or are perceived to belong to, is the visible cue to their caste. It is the historic flash card to the public of how they are to be treated, where they are expected to live, what kinds of positions they are expected to hold, whether they belong in this section of town or that seat in a boardroom, whether they should be expected to speak with authority on this or that subject, whether they will be administered pain relief in a hospital, whether their neighborhood is likely to adjoin a toxic waste site or to have contaminated water flowing from their taps, whether they are more or less likely to survive childbirth in the most advanced nation in the world, whether they may be shot by authorities with impunity.

South Shore was one of the last white strongholds on the South Side, the completion of a cycle that had begun when the migrants first arrived and started looking for a way out of the tenements. There were fifty-eight bombings of houses that blacks moved into or were about to move into between 1917 and 1921 alone, bombings having become one of the preferred methods of intimidation in the North. In neighborhood after neighborhood, with the arrival of black residents the response during the Migration years was swift and predictable.
