Take this quiz!
I strongly encourage everybody to take it!
As of this writing, nobody has scored higher than the mid-70s, with many falling below 50%. That, of course, doesn't surprise me; the United States is noticeably lacking in atheist libertarians.
Be sure to post your scores!
By the way, it seems that OKCupid forces you to register after you've answered the questions but before you see your final score. No worries - you can make the information up! They don't even verify the email address.
