Too Many Catholics?

According to a recent survey, Catholics comprise 25% of the American population. As things stand, the Supreme Court is currently home to five Catholics: Antonin Scalia, Chief Justice John Roberts, Clarence Thomas, Samuel Alito, and Anthony Kennedy. If Sonia Sotomayor is confirmed by the United States Senate it would mean that six of the nine justices or 66% would be Roman Catholics. Some people think that's too many.
