Constitutions, whether written or unwritten, are moral visions. This is why a morally neutral society can't exist. It's also why a morally neutral judge can't exist, he has to rule on some moral vision, whether it be his own or the currently dominant constitutional one.

This has implications, most of which aren't very nice. At the very top, moral visions that are not too different can reach a compromise, but those that are incompatible result in a culture war. And if you don't take some un-nice, un-'why can't we all just get along' paths, you lose the war.
