It isn't the ones that don't believe in God that are so bad, at least they aren't hypocritical. It is the ones that claim to believe in God, which irritate me more. If they believed in God, they would have more respect for his creation. They are all liars and hypocrites, willing to sacrifice a human life to make a name for themselves. True that moral arguments don't work with some of them, but it is really the only valid argument to this question.
Always be sure to ask them “which god”. Sometimes they tell you that’s a trick question.
