I already posted the Wikipedia description; the one stating "most inclusively". If you are going to pick a definition of atheism that doesn't cover all atheists, then you aren't making a point on atheism itself, but rather a specific brand of atheism.
Disbelief (as in non-belief) is the absence of belief. Disbelief can be a refusal of belief, yes, but like most words, it has multiple meanings. As I've used the word "non-belief" here repeatedly, maybe I should have clarified that I am using "disbelief" as a synonym.
If you want, I'll change my argument to suit your use of disbelief. I don't disbelieve, I don't believe. If disbelieving involves rejecting belief, then I'm certainly not a disbeliever, but I am a non-believer, since I don't have any belief in God.
