I found myself returning to some words of Martin Luther King’s, about how “the arc of the moral universe is long, but it bends toward justice.” I did not believe them anymore. The arc of the moral universe does not bend toward justice. It has to be bent, and this requires sheer force of will. It demands our sharpest focus and most concentrated effort. History does not move in a straight line; it has to be dragged, kicking and screaming, all the way down the line.
