I think that is slightly different to the traditional meaning of the term.
So would you agree that atheism isn't really a position at all? Is it just a psychological state?
Well that's simply because it's a retarded term. It pigeon holes people a set belief. I once had someone try and tell me what I believed when I said I was an Atheist and they got annoyed when I said they were wrong.
Theism (from wiki):
-Theism, in the broadest sense, is the belief that at least one deity exists.
Atheism therefore is the opposite. The lack of belief in deities.
You'd have to clarify what you mean by psychological state. An Atheist isn't a specific type of person, it's just someone with a lack of belief in higher/supernatural powers. Just as a scientist can be a Theist I think someone in a Church choir could be Atheist.
