Another 100% atheist here. I don't have any doubt that this universe is a natural phenomena and no "super"natural entity exists. A non-corporeal entity is an oxymoron of epic proportions.
So, yes, "real" atheists exist.
But, for the record, being 99.99999% sure is pretty much the same as being 100% sure.
You believe infinitely less than a 100% atheist if you are only 99.999999999999999% sure
But seriously I now believe that there are atheists. The metric of 99.9999999999999% sure is as sure as anything possible. Virtually no honest person can be 100% sure of anything so to use that as an excuse to claim someone is not an atheist is an unreasonable metric.
As for my friend he does indeed exist. I use him as an example because he says such interesing things and I am constantly doing battle with him on facebook.
nam, I do put my thoughts beliefs on this forum, in most of my posts even where I am using my third party battles.
