Maybe Roberts said that if he felt that his personal views would cause him to be unable to fairly apply the law as a matter of conscience, he would recuse himself. What do you think? Of course, such a recusal on those grounds has NEVER happened, ever, so far as I know. Judges always feel they can be fair, always. They sometimes recuse themselves on the basis on conflict on interest given the parties involved. That is about it.
This doesn't pass the smell test...and it's already been posted under a different newspaper banner.
