Perhaps to clear up some confusion and frustration.
There are two different definitions for agnostic: the "popular" one and the technical one.
You are operating under the popular definition of agnostic, which is to describe someone who neither believes nor disbelieves the existence of god.
(Which I believe is actually a pretty rare thing, since it requires a perfect balance: you believe there is equal reason for believing in god and equal reason for not believing in god. For most people, in my experience, the scales are tipped one way or the other, and they just call themselves agnostic because atheist has a bad connotation and they think that means they have to claim to know for sure that god doesn't exist.)
The technical, historical definition, that most of us here on RF use, describes someone who doesn't claim to know whether god exists or not. I was changing up the wording for the sake of the argument. That of course is also my definition.
This definition has nothing to do with belief; it has to do with knowledge. I can (and do) believe that god does not exist, but I do not know this for sure, hence I am an agnostic atheist.That would make you an agnostic IMO, however if you want to make it more precise using that wording then o.k.
