I see what you mean.
To me atheism is a position statement, as is agnosticism, or
theism.
I would class you as agnostic, in the sense that you do not
come down one way or another, while crashfrog (like myself)
is an atheist -- there is no God as far as I am concerned
but hey if you can show me I'm wrong that's fine. Admitting
that you might be wrong is not the same as not having made
the belief-choice (and atheism etc. are just beleifs after-all
... it's just that mpost atheists have their reasons for
beleiving that way ... more so than 'I was brought up in
[insert religion of choice].'
Theists tend to be of the 'There IS a god, show me I'm wrong
and I'll redefine everything so that there is still a God.'
