So do you understand why I would group your set of beliefs on divinity in the same category as other sets of beliefs on the subject?
I understand what you are saying and I'm telling you that you are patently wrong. Atheist has a very simple meaning. The only thing it tells you is that the person does not believe in any gods. Are you aware that there are Buddhist atheists? The Buddhist part is essential to knowing what their belief system might be. In my case, if you were to ask of my belief system, I would tell you that it most closely aligns with secular humanism. Without that piece of information, the only thing you know about me is that I don't believe in any gods. You might also find it interesting to know that I was the president of a church - as an 'out' atheist. Saying that atheism is a religion is like saying that bald is a hair color. They may often be proximal, but they are very distinct things.
