Sunny,
Excellent post, and I will bet that a lot of lurkers see themsleves in you. Welcome to the road to atheism. I went through a simialar journey post-JW; after lots of study and research I became agnostic, then an atheistic leaning agnostic and then an atheist. I didn't make the transiition without years of study, research and meditation (and almost all of it was before the Internet's full capabilities to assist me - I would have loved to had Cofty's threat available to be 20 years ago). I'm so glad you understand that the bible is probably the weakest tool for theists. In fact I would say it may be the best argument atheists have.
Thank you for posting the link. Tyson is correct; the best argument against theism is the scientific method. Upon completion of my master's degree, I was a full fledged atheist. I'm working on a PhD currently, and I can't imagine anyone with advanced degrees being a theist, but as Tyson points out, it will never go to '0." Some people need a personal god.
Those of us who don't need a personal god, IMHO and suggested by scientific studies on the topic, to behave and be ethical are more highly evolved. It is where all humanity needs to be in order to solve the myriad of problems facing us. Religion will always be more divisive and destructive than otherwise. Does anyone really think the Christians, Muslims, Jews, Hindus, etc. etc. will ever truly get along without wars, terrorism, economic disparity, etc.? Will secular humanism solve all of the problems? Probalby not, but it has a much better chance.
Good luck to you, and I will be preparing your official atheist ceritificate.
