However, one of those smug atheist truisms which I have generally found to be true no matter how smug it may be is that atheists tend to know more about religion than religious people. It's no surprise that most Christians have never read the Bible (even those who believe in Biblical inerrancy - I mean, holy shit, if I believed a book was the literal, absolutely true Word of God I would read every single word repeatedly like my immortal soul depended on it, ya know?), and that many American Christians have completely wrong ideas about what the U.S. Constitution actually says about religion, what you can and can't teach in school, etc.
So test your knowledge with the Christian Science Monitor's Are you smarter than an atheist? poll.
This atheist scored 30 out of 32. (I missed one I should really have gotten right, and missed another because I just didn't remember.)
(There is a shorter version conducted by the Pew Forum here which includes a report on average results nationwide, by religious affiliation or lack thereof.)
Hat tip to joreth for posting about this and pointing out legitimate issues with how the CSM is likely to use the results.
