I agree completely, as long as that "diversity" is democratically chosen.
However, the concept of "diversity" is not part of our present civic "religion," enshrined just this summer as a "constitutionally" sanctioned value, because the American electorate has been clamoring for it for the past five decades (Ever hear in an election campaign in the past few decades someone ask "I wanna ask Candidate Smith this question: when am I going to get to live next door to some Somalis?????").
No, it's been imposed on us from "above" by unelected bureaucratic, academic, media and judicial elites. As such, it is a totalitarian ideology, not a democratic one. And the fact that it is an undemocratically imposed "value" overrides all the benefits (like cricket playing in NY parks) that you can postulate.
