Yes, actually. Me for one. As I described. I do not believe nor disbelieve, both are logically impossible. (For me)
Since "I do not believe nor disbelieve" that makes me an agnostic, but agnosticism is a subset of atheism. It's just a matter of definitions here.
The substantive belief (or lack thereof) doesn't change, no matter what label you assign.
You sound more like an ignostic.
