The point of DEI is to have the widest possible distribution of life experience among the group. Of course 12 white, blue-eyed, blonde men would have different life paths, but if you project them on 2D graph and draw a circle around them, then the distance to the point of white blue-eyed woman would be about 5 diameters of that circle, and to the point of black transgender person - about 15 diameters.
The most meaningful and useful diversity would be that of social class, and yet that's the one kind of diversity the DEI bureaucracy isn't interested in diversifying.
