The most important reason anyone is an atheist

[MitchBenn]

Yours works like this:
Demand evidence, don't listen, piss and moan that your not convinced, insult Christians.

False.

It is more like this:

Atheist: where's the evidence?
Theist: right here.
Atheist: that's not evidence.
Theist: Sure it is.
Atheist: If it was true evidence, it would be accepted by those intelligent enough to accept it as evidence.
Theist: You're just close-minded and stupid.

Actually it's this:

Theist: Look! This evidence PROVES God exists!

Atheist: Erm... No it doesn't...

Theist: Well of COURSE it doesn't! You can't PROVE God exists, you shallow materialistic FOOL!
