B2P,
You seem to be trying to assert that there is a difference between "belief in a god" and "the existence of this god". There really isn't any difference. Ultimately, it all comes down to your belief. You just can't stipulate to your god's existence as though it is factual. The only thing provable is that you believe in your god's existence.
You said: "Just because people don't believe in something doesn't mean it doesn't exist."
Certainly you are intelligent enough to realize that the reverse of that is very true. Just because people believe in something doesn't mean it exists.
To "assume god is real for a second" makes it nothing more than a hypothetical discussion, and so, isn't really germaine to the discussion, unless the debators all stipulated that it was merely a hypothetical discussion.
I only read this last page of this discussion so I may be re-iterating something already said, but I think it is folly to piggy-back morality onto the back of religion. Morality has as much to do with our religious choices as it does with the choices we make regarding the sports we prefer, or the foods we like, or whether we wear boxers, briefs, or lacey panties. I imagine that Rrhain has been trying to point out to you that the fact that atheists are just as moral as any other demographic proves that religion and morality aren't related.
