But then...

...isn't theism also a disbelief? A disbelief or lack of belief in the non-existence of God or gods.

It seems like the 'lack of belief' part is kind of sloppy, because you could end up calling an agnostic a 'theistic atheist', or an 'atheistic theist', since an agnostic lacks beliefs in both directions.

'Agnostic' seems the better term if you're emphasizing lack of belief.
