Everyone behaves in a hypocritical way from time to time, even "atheists". Hypocrisy is not who you are, it's how you act and your attitude. You can't be an angry but you can behave in an angry way, or even have an angry attitude. Why do atheists use the Lords name in vain when they profess not to believe in Him? If He didn't exist then the name would be meaningless. If they were not hypocritical they should cuss in the name of Darwin or something.
