The next time some academics tell you how important diversity is, ask how many Republicans there are in their sociology department.
Whenever someone refers to me as someone "who happens to be black," I wonder if they realize that both my parents are black. If I had turned out to be Scandinavian or Chinese, people would have wondered what was going on.
Social values in general are incrementally variable: neither safety, diversity, rational articulation, nor morality is categorically a good thing to have more of, without limits. All are subject to diminishing returns, and ultimately negative returns.
To those who feel that their values are THE values, the less controlled systems necessarily present a spectacle of "chaos," simply because such systems respond to a diversity of values. The more successfully such systems respond to diversity, the more "chaos" there will be, by definition, according to the standards of ANY specific set of values- other than diversity or freedom as values. Looked at another way, the more self-righteous observers there are, the more chaos (and "waste") will be seen.
