I just found this forum and wanted to introduce myself. I am a retired university scientist (biology) living in rural SE Arizona and consider myself to be a committed non-theist. I came to this stance sort of through the back door; I never had an ah-ha, epiphany moment. My parents were not particularly religious so I avoided any early religious indoctrination. And, when I was old enough to think for myself, I found that I could never find any logic or internal consistency in any of the major faith systems and thus never was tempted to adopt one. For these reasons I have never been religious in any sense of the word.
I have, however, learned through the years that it is generally best to keep my mouth closed about my lack of faith if I wish to get along with neighbors and acquaintances. The strongest stance I will take is arguing that a person does not have to be religious to be moral. But, frankly, I have found that most people do not question what they have been taught so conversations tend to deteriorate to me listening while they tell me the way it is; there is not too much theory or philosophy in the lectures I get, just dogma. Fortunately, I am an introvert so not having a lot of friends does not bother me much.
