If diversity is so great, why did the Armed Forces used to teach unit cohesion?
Bings to mind sitting in the enlisted men's club at NOB Norfolk in (about) 1962, with a black shipmate from Chicago. A TV was showing some of the violence against civil rights marchers. He said (something on the order of) "There's a lot of your people here, and a lot of my people, and we're getting along OK". I think my answer was "That's because we're all blue". I served with a few whites and a few blacks who had "attitudes" but most of of us got along.
