It is now July 2015, the midpoint of a summer that feels like no other in Supreme’s memory. Two weeks earlier, a white supremacist had gunned down nine Black worshippers at a historic church in Charleston. The country seems ripe for another civil war, with a cohort of white Americans defending their Confederate flags while Black activists mount a movement that has enshrined Eric Garner’s name. In Texas public schools, new social studies textbooks have minimized the role of slavery in the Civil War, while a geography book depicts slaves as “workers” who came by way of “immigration” from Africa.
