Well, at least you've acknowledged it's not a Dem thing only. BTW, Eisenhower picked Brennan because he was Catholic; Reagan picked Scalia because he was Italian. Anyway, the big question:
What about Neil Gorsuch? Was he selected based on superficial, irrelevant characteristics? Or does the DEI stigma only attach to minorities? I think you're actually creating a system in which white men are seen as the default and a decision to hire, promote, appoint, etc., a white man can't be based on superficial characteristics. Alone among people, the white man enjoys the presumption of merit even where it is plainly inappropriate. Gorsuch was not well known, and to the extent he had a reputation, it was mostly as a fringe judge with bizarre views. So why was he the choice?
Why has the modern GOP never nominated a minority candidate to the Supreme Court, with the exception of the obviously token hire Clarence Thomas? Is that DEI? Or is it only minorities who have to battle that perception?
