I BELIEVE GOD DOES NOT EXIST.
As for your theory, the number of posts is a rough indicator of how long a person has been thinking for themseelves, since True Believerâ„¢ Dubs wouln't be here at all, or will only lurk until they gain the self-confidence and courage to make that first post. I believe that the longer a person thinks over what the WTB&TS has taught them, the more likely they are to discard those teachings.
The point has been made before that most theists are only "one (or two) god(s) away" from being atheists. For example, Christians usually do not consider Allah, Vishnu or Odin to be valid "gods." Or the Christian may claim that Allah, Vishnu and Odin are really "anti-gods" - the gods of FALSE, demonic, satanic religion.
Most theists believe in a good "god" and a bad "god." Some might say that the "bad god" doesn't exist, but that separation from the "good god" is the source of evil. Whatever. If a person come to view his previous belief in dueling gods or a single lone god as unrealistic, he is an atheist.
To my mind, people who say hey are "agnostic" are simply trying to please everyone by not appearing "confrontational." Sitting on the fence is too painful for me. There is no objective, verifiable evidence that any spirit creatures exist or that "hidden realms are anything other than ideas or delusions.
Theists can be no more certain of their world-view than atheists, so in a very broad sense we all "DON'T KNOW" and are thus AGNOSTIC.
Let's agree to flip a two-sided coin. Does it come up GOD or NO GOD? Our coin has no thickness, so it cannot land on its edge.
