This is what drives people like me crazy. I will readily admit I choose to be atheist based on the information that we have at this moment in time.
However, most believers, (pick any form) will tell you they know the one true god and everyone else is full of shit. I have only met one or two true believers who will admit they CHOOSE to believe in whichever god they believe in. They KNOW they a right. This thinking leads to war, genocide, and terrorism. It's dangerous.
