I certainly do think that his religious identity is marginal. But then, many American presidents including Lincoln and probably Washington were not Christian. (The most recent was Taft, who was a Unitarian and stated in so many words that he did not believe in the Incarnation.) If Obama were a Muslim, he would be quite outrageously out of skew with the average - rather like a family of Egyptian diplomats I knew in Rome, whose teen-age daughter used to laze around the semi-public local pool with my sister in a bikini in the summer, and would consider aloud becoming a Christian because she had liked Jesus Christ Superstar so much. It is his ignorance, and not his knowledge, of Islam, that bothers me.
