Mr. Rock,

Nice piece. You will get pushback from those who would seek to divide us. The takeaway is intuitive: separating people into groups tends to create barriers between them. You should also take a look at what having affinity groups on campuses does to people. Short version: it increases intergroup tensions and reinforces stereotypes. The diversity industry profits from destroying the fabric of society and driving people apart. It's cynical, counterproductive and wrong.
