]Lets ignore religion for a moment. Let us take a child that believes in Santa Claus. What happens on Christmas? The child will expect presents.
If the parents teach them to expect presents they will, regardless of the presence of Santa Claus or not in the equation.
What happens to a child who doesn't believe in Santa Claus - and furthermore - never heard of either Christmas or Santa Claus? The child will not expect anything on the 25th of December.
All you're talking about is learned behavior and expectations. We all have those, whether religion plays into it or not.
I hope you now understand how non religion cannot mess things up (because of the lack of belief in a god).
It definitely can screw things up - but because of other reasons that are available and in use today. But at least the religious ways to screw things up will not be there
The only way that non religion could screw things up more than religion would be if the ONLY way you can get morals is from religious texts. And that's an abherant assumption.
I'm sorry - I don't see how this has anything to do with the price of milk. All you seem to be saying is that both religious and non religious ideas can influence bad behavior - which is what I've been saying.
I've added, however, that ultimately we are each responsible for our actions regardless of what we've been taught.
