As we know, religion is rarely a choice. People rarely apply very hard standards to their religious beliefs. They tend to be cultural (i.e., you grew up in a social environment that preferred one belief over another.I'm sure the other side has its own bias too, but I think it's different. The difference is religious people seem to need their religion. If they were confronted with proof that their God isn't real I think a lot of them would be very broken on a spiritual and emotional level. Conversely I think if agnostics and atheists were confronted with proof that God is real it would have a different kind of impact. I think many atheists would be salty over being wrong, but I don't think it would destroy them in the same way. The purpose in their universe doesn't hinge on God in the same way. Personally, as an agnostic that was formally an atheist, I'd be thrilled to find out God really exists. It would simplify the universe and bring me a lot of comfort, which is probably what religion does for the religious.
Why does it matter? I think religious people, because they need this more, will bend and go to any length to avoid absorbing the kind of scrutiny that would make them question their God. They are by far the more desperate and stubborn ones in this debate. It's not about logic and facts for them. They need this, so you're never going to change their minds.
One's religion is, with near exclusivity, a matter of parentage and place of birth. Raise a child in an islamic nation of islamic parents and the child will be Moslem. The same thing for a Hindu child in a Hindu home or a child from the US in a christian home.
A person's happenstance of geographic place of birth and parentage is, overwhelmingly, what drives their religion.
If this forum were in India, overwhelmingly, the religious people would be making the same arguments for the Hindu gods that the Christians are making for their gods.
