In other words the position is "don't know"? or "don't believe"?
I think one can see it as a spectrum, but an agnostic atheist is a misnomer.
The agnostic says I don't know
The agnostic atheist : I don't know and don't believe
So does the atheist say : I know and I don't believe?
Why not? I don't know whether the bits of cucumber I put down the garbage disposal this morning turn to gold on the way to the sewer or not. But I don't believe they do. I think I'm safe in my belief. I'm both agnostic with regard to cucumber turning to gold -since I can't verify the process, and atheistic with regard to the belief in golden cucumber bits dropping into the sewer.
There's nothing wrong with believing that something doesn't exist and still admitting that one cannot know for sure whether the belief is correct. In that regard, Photizo is right for a change. Rationalists who have come to the agnostic-atheist conclusion are unwilling to believe in the supernatural since there is no evidence to suggest that the supernatural either exists or is necessary. There is, however, a preponderance of evidence that the supernatural is a human construct, designed to explain that which humans are ignorant about.
I am, however, willing to believe anything that has legitimate evidence to support it. Contrary to what Photizo might want to believe about those that reject his superstitions.
