@Anonymous Coward - You forgot to mention all possible combination
of one or many of the criteria you mention which means you will always have a class that is not represented. For example, a black Jewish lesbian person with physical disabilities.
In my opinion what they call diversity is, for all practical purposes, unattainable. With every new binary criteria you add, the number of specimens required to be diverse will have to double. Some category will always be discriminated.
