The only form of diversity that should matter in higher education is intellectual diversity.
Diversity also has the pleasant aroma of kindness and generosity.
To be in favor of it speaks to one's openness to the world. To be against it is evidence of small-mindedness. The Supreme Court's inaction may not amount to much. The case in question was moot and other more potent cases are on their way. This is but an arrogant fantasy, a dream world in which an all-powerful self can borrow freely from other cultures, discard disagreeable customs, and arrange the whole to his own satisfaction.
