Here you have another atheistic beliver. For even Atheism is just a´ belive. I was a JW for over 20 years. Even an elder.
during these 20 years I remember concentration in pushing away all "odd" questions that my congr. and GB never spoke about. Then I decided to find out what was real, and what other thinkers already had thought. I signed in for University studies for over 3 years. Subject History of Ideeas and Science, Philosify, and Archoeolog. From my last year in University I was turned in to clean clear atheist, even though one of my professors also was serving as a catholic priest. I often wundred why such an educated men, turn into religion again? His answer was that Religion and science has nothing to do with one another. But just the searching for Good shows that the human brain is dedicated to find security, knowledge, stability and some/any answer that satisfy our hunger for knowledge.
Perhaps you could start with reading Karen Armstrong "The battle for Good". The book goes through many fundamentalistic believs during a 1000 years. (Karen was a catholic nun for over 10 years and is now a professor in Theology at Oxford.) Her ideas can show you very much about how faith does much harm.
