Ah, Ok I think I understand your point now. You are saying that science (specifically genetics) may provide insights into why people want/need belief structures, and that it may be dangerous to the psyche to not provide it with these
hmmm. It is an interesting question, but one I feel has not been thoroughly researched yet, and certainly no conclusions have been drawn. I would also add that even if there is a genetic predisposition to desire a (quite obviously false) belief structure that it does not mean that this is healthy. And yes I use the word "Truth" for decribing reality as we can never quite define it. Philip. K. Dick. said 'Reality is that which when you stop believing in it, doesn't go away' - lol in that case religions are certainly reality.
Anyway this is getting off-topic although I appreciate your thoughts on the matter, Skybird.
back to the OP - I think anything divisive is harmful and discourages ethical behaviour, and as a flip side, anything inclusive helps and encourages ethical behaviour.
