I'm not Morkat (whom, if Joe is correct about his identity, you won't be able to extract a rational argument from.) But I found your quesiton interesting, so here are my answers:
FreeDuck wrote: A court in which 5 of the justices are brothers.
I would be worried for reasons of cronyism, but not for lack of diversity.
FreeDuck wrote:A court in which 5 of the justices are women.
No problem at all.
FreeDuck wrote:A court in which 5 of the justices are from the same state.
I would be worried for reasons of cronyism, but not for lack of diversity. And I would be somewhat less worried than if the justices are brothers.
FreeDuck wrote:A court in which 5 of the justices are slave owners.
This one is too far from reality to be easy to answer. But if you allow me to change it into "an
1880 court in which 5 of the justices are
former slave owners", no problem. In the early years of the Federal Republic of Germany, we had courts with larger shares of former Nazis, and they generally decided their cases justly once our democratic system was established. (There were some exceptions to that rule.)
FreeDuck wrote:A court in which 5 of the justices are former oil company executives.
I would be worried for reasons of cronyism, but not for lack of diversity. I would be somewhat less worried than if the justices are brothers, but somewhat more than if they are from the same state.
FreeDuck wrote:A court in which 5 of the justices are former members of the socialist party.
No problem at all. My comment about former Nazis in early democratic Germany applies to this example as well.
I'm just noticing that I haven't stated my position about the five Catholics on the court. They concern me about as much as the fact that Alito's nomination would increase the number of "Tony"s to three:
Antonin Scalia,
Anthony Kennedy, Samuel
Anthony Alito. Because the share of "Tony"s in the general population is only a small fraction of the share of Catholics, this imbalance is even grosser than the Catholic overhang.
(PS: Nice to run into you again, FreeDuck. I hope your new line of work is boring so you come post here more often.)
