I think the OP doesn't either trust the declared goals of "countering institutional prejudice" and "improving the quality of the student body", or doesn't believe that DEI actually does anything relevant in this sense.

Even for banal acne treatments, proof of safety and efficiency through several stages of trials is required before people are actually subject to it.

With DEI, we are just expected to believe that it actually works and should be applied across the country because some smart people say so.
