<< Atheists don't believe in the existance of God, therefor they have a belief but not a religion.
Agnosts on the other hand don't claim to know whether God exists, but want proof first. Would they fall under 'Other', or 'None'? >>
I consider myself to be agnostic. However, I'm not in a situation where I want "proof", for even with definitive proof of God's existence, I would still not worship God. For me, the idea of "worshipping" anything is silly beyond imagine..
All religions are equally stupid.
