What is the most condescending reason used to explain atheism?

The fool says in his heart that there is no 'god'. I probably don't have it exactly quoted, but I figure everyone will get it. Bottom line: Calling someone a fool is an insult and a TOS violation. And it is infuritating coming from people who believe in talking snakes and talking donkeys. Then they go on to say that atheists choose atheism so they don't have to answer for their sins. So, without knowing who is on the other end of the message, they start throwing rocks about how much of a sinner that person is. Talk about narcissistic and holier-than-thou.
