Effectively there are 3 stances; Believe in God or Gods/Do not believe, but do not deny\ don't know (fence sitters)/Disbelieve in God or Gods. Practically, these are referred to as Theists/Agnostics/Atheists. This is usually done to avoid all these semantics arguments, which are a favorite of anyone who is losing a debate to try and derail the opposition's train of thought and thus win by default.
I personally describe myself as Agnostic because of my personal understanding (a.k. 'belief') that one (or certainly 'I')
cannot know the Truth, whichever way it might be. On top of this I adopt a (soft) atheism standpoint insofar as I simultaneously do not believe (as opposed to someone who is an agnostic and a believer, e.g.: "while it is the case that logically it cannot be proved, I subscribe to the religious POV"; and the agnostic strong atheist: "there's not, of course, but I can't prove it").
Think "Political Compass", with Authoritarian/Libertarian axis as well as standard Left/Right. I tend to think of belief under Theism->Strong Atheism (Weak Atheism being centerline) on one axis, Gnosticism/Agnosticism along another axis ("I know" -> "I cannot know", with "I don't really know" in the middle), Apatheism opposed to Devotion on a third (insofar as the former directly opposes the tennet's of Pascal's Wager[1]) and possibly Evangalism/passivity on a fourth (if you shuffle the previous one around a bit to make room for the distinction). Add more, to taste, possibly including an honesty/hypocritical distinction which might help distinguish certain televangelists from some other prominent preachers.
I site myself centrally under the Theism/Strong Atheism axis (I tend to look religously inclined to strong atheists, and a denial-type 'atheist' to theists, so it's soft atheism for me... explicitly soft because of my pondering, I suppose), strongly Agnostic (I am convinced that there is no logical way one could prove
or disprove a god's existence, inclusive of apparent manifestations), a fair bit apatheist (in that I'm probably relying on earning merits for "he meant well" for any hypothetical checking of the boxes at whatever Pearly Gates equivalent I might attend, if that's what happens), far more Evangelist than I'd like (witness this convoluted explanation of my world-view) and I'm not sure about the honesty/hypocrit side (I'd like to say I'm honest, but then I would say that if I weren't, so it's not for me to say).
Kettle. Fish. Or barrel, thereof, to be shot into. Your choice.
[1] If there's a God, He's going to know if you're worshipping "just in case", best to be true to yourself and not demerit yourself trying to cover your arse. The middle ground may be those who will pay lip-service (or adjust their outward display of their internal belief) to whatever deity happens to be
de jour without worry that it would be ultimately 'received' by an incompatible deity. At the extreme Devout end, one would find the various martyrs to whatever cause exists. Inclusive of Dawkins-esque types who devoutly display their explicit and strong non-belief (which, in some times and places would get you 'martyred' as quick, or quicker, than alternate beliefs).
