Gonna have to disagree with Moose here. I tend to think that, at a push, most atheists would agree that they cannot totally deny the possibility of the existence of God/Gods without moving into almost a "faith" position. So technically, one could regard them as agnostics as well.
I don't think you really are disgreeing with him, in fact you seem to be saying something pretty similar but you have just come to a different conclusion as to which label should be applied to those with no compelling belief in, yet who recognise that they can't know for certain that there is no, god.
I suspect that Moose's classification is more in line with the thinking of a number of the theists on the board. I'm sure Ray (Herepton) would classify a large proportion of those who have described themselves as agnostics as atheists.
This may be one reason for the disparity in views on atheists outnumbering theis that NJ brought this up to solve, a lot of those who self identify as agnostics obviously appear to be atheists to many of the theist members.
As for me, I am another who is philosophically agnostic but functionally atheist. So I would put myself in the agnostic category.
TTFN,
