How likely is it that the world’s 1.3 billion Muslims will wake up one morning and abandon their ancestral faith? Even if you are a ferocious Sam Harris-style atheist who thinks religion is completely stupid--the province of shysters and fools--you have to admit it would be quite astonishing if that view persuaded the devout anytime soon: This Koran, which I thought was dictated to the Prophet by an angel, is totally ridiculous and poorly written to boot! Muhammad, that child molester, most definitely did not fly to heaven and back on a winged horse! What an idiot I was to give these notions a moment’s credibility! There’s no question in my mind that horror at militant Islam and fear of Muslim immigration lie behind at least some of the current vogue for atheism--you don’t make the bestseller list by excoriating the evils of Lutheranism or Buddhism.
