No Supreme Court Justice is seated to represent a single group. If Clarence Thomas had that for a mission he couldn't judge any case impartially.
What he is there for is the Law. He judges the true or false in American justice. Perhaps not always efficiently; but he has the US Constitution to guide his performance. AND, for Perry's information, he has the office of Supreme Court Justice for life. Isn't that grand?
No one can disqualify him for his color. That ought to comfort a black person.
