In the afterward to his brilliant and captivating "Arc of Justice," the story of a pivotal but largely forgotten incident in America's Civil Rights movement in 1925 Detroit, historian Kevin Boyle writes that segregation is so "deeply entrenched" in this country that it can't be uprooted. Even today, he writes, black and white neighborhoods across the United States are "separated by enduring discriminatory practices, racial fears and hatreds, and the casual acceptance by too many people that there is no problem to address." It's a stunning statement to many, no doubt, yet surprising in its obliqueness: a century of lynchings and race riots following the Civil War are over, having taken a full hundred years to slow to a crawl and then die. But many vestiges of discrimination remain. Because the practice has continued, many of us give no pause to the one singular thriving aspect the black/white conflict, that of racial segregation in our cities and towns. Residential segregation continues to go unchecked because, from the comfort of our living rooms and our front porches, we continue to proudly (but blindly) proclaim that - as some citizens of Detroit in 1925 proclaimed - we harbor no prejudices.
