I keep looking at Supreme Courts and I am having trouble seeing the excluded men and the excluded white people.
Whilst true that these categories can be shallow ones, it's the deeper differences of experience that correlate with those outward appearances that are essential to having a broadly representative court. And don't forget that part of the experience of being, say, black is in HOW THE LEGAL SYSTEM TREATS YOU and what biases lie therein. Which, by gosh, might have some bearing on matters of jurisprudence.
