I think this is a primary sticking point between us, and until we can resolve it I'd prefer to hold off discussion of the other points here.
So yes, I'm quite serious. I truly cannot understand your point here. I maintain that NOT believing in something is very different from believing that something is not. I see a large difference between saying, "I do not believe in God", and saying, "I believe there is no God." The first is a statement of disbelief while the second is a statement of belief. It is POSSIBLE to say both, but saying the first does not necessarily mean that the second is true. In my mind what you are seeming to imply is like saying, since I do not believe in RED, therefore I must believe in GREEN. Both MAY be true, but neither is dependent upon the other.
