My biggest disappointment about the study is that it left out the largest category: closeted atheists. They are the elephants in the room and the ones most likely to change the culture by coming out. However, many of them feel they have good reasons not to, including potential ostracism from family and friends as well as loss of income or employment. Another unmentioned category is what I call functional atheists, those who may or may not have vague supernatural beliefs that play no practical role in their lives. They live as if there is no god, just as all atheists do.
An atheist is simply someone without a belief in any deities. But disbelief in gods doesn’t describe individual atheists any more than disbelief in the divinity of Muhammad, Krishna, and Zeus describes individual Christians. Everybody disbelieves in some gods; atheists just disbelieve in more gods than theists do.
