PLAYBOY: President Obama acknowledged “nonbelievers” in his inaugural address, which caused a fuss. But when you consider religious belief, one of the largest groups in the U.S. is atheists and agnostics. Why do they get overlooked in political discussions?

DAWKINS: It’s a good point. Of course, it depends how you slice it. Christians are by far the largest group. If you divide Christians into denominations, agnostics and atheists come in third, behind Catholics and Baptists. That’s interesting when you contrast it with the lack of influence of nonbelievers.
