To me every example of diversity basically has been the concept that "there are too many white people in the room." And to a smaller degree that "there are too many straight men...".
I've never seen this applied to non-whites, at least not to this degree. In fact, 100% black-demographic teams (or businesses or organisations) are oftentimes praised for being "authentically black".
IMO, the way I see it is once a productive homogeneous group (which by definition is composed of members that are able to agree with each other and engage in actual progress rather than in-fighting) puts in the effort and spends the time building the infrastructure/business/etc and makes it successful - then other groups see this as an opportunity to get something out of it... "Diversity for the sake of diversity" only comes in at the end, never at the beginning.
It is also odd that when someone says diversity is our strength, they never really share the actual details of that strength.
To me this is a turning point for a company that goes from being work oriented to becoming a race/gender oriented cesspool where everything is about your color, genitalia, and gender.
