Not much comment from me here, but I recommend this article from Dance Magazine:

True diversity is when a person’s differences are welcomed, desired, and integral to the environment such that their absence would diminish the product. Exhibit A: New York. So many different races and cultures in one place create a singular energy and flavor. That’s its beauty. We may get on each other’s nerves, but we all have to be here to make it magical. We have made progress, it’s inevitable when we are living the “browning of America.” But sometimes it’s not where you are but where you are not that speaks volumes. It’s a black thing, but I think you can understand.
