You answer a set of questions and it tells you which religion or belief system best suits your statements - atheism, agnosticism and satanism are also in there.
It says I'm a satanist too. Though the author seems to think that having a strong preference for personal freedom (as I do) equates to devil-worship, so I'd take that with a pinch of salt.
It tells me: Your beliefs are most closely aligned with those of paganism, Wicca, or a similar earth-based religion. You may also follow a Native American religion
I got 100% Atheism which is accurate. 100% Satanism which is not true... Something tells me this quiz was devised by someone pretty religious... I got 83% Buddism though which is interesting. And I dunno how I could score 50% on agnostism if I also scored 100% atheism... A pinch of something's needed that's for sure!
