I’ve run into those on FR and told them that if they want an excuse to reject God, they need to find a better one because that’s pretty weak.
I try to be sympathetic towards other viewpoints. But if I were an atheist, I sure wouldn’t behave or act like most of them do. I recognize that even if the Old Testament stories aren’t historically true (a view I don’t share), they still would hold value as mythological lessons in morality ...dismissing the entire Bible because “snakes and donkeys can’t talk” is a pretty bone-headed way of looking at it.
