The first thing that came to mind when reading the OP was something Richard had said in a Discussion between Richard and PZ Myers - At one min.. He says that at Oxford College when he happens to be the senior fellow he says the Grace - Halfway down page. He does so because he thinks it is polite, a tradition and it would be petty to refuse to say Grace which would give atheism a bad name. The prayer is obviously contrary to Richards beliefs, but he recites them for the above reasons.
Edit: I apologize, on second thought I realize it’s not really related to the topic. Besides it gave PZ a chance to say he was less of an ‘appeaser’ than Richard.
