What happened to Protestants on the Supreme Court?

News reports tell me that retiring Supreme Court justice Stevens is the last Protestant on the high court. Everyone left is Catholic or Jewish. This ought to say something about the miserable state of the Protestant church in America. Jews and Catholics have a solid tradition of absolute right and wrong that goes back to the time of Jesus and before. Modern Protestants have bought into a relative morality that can permit a lot of dreadful things. Seems like when selecting honorable men to serve on the high court the body politic looks for men who believe in absolute right and wrong, rather than a slippery relative right and wrong.
