As an atheist there are few things more infuriating than some ass hole saying "there is no morality with out God." Of course I know that majority don't believe such garbage but there a few (some very vocal) who do. Of course its complete bull shit. Morality Dose exist with out God, in fact I can easily think of fore main sources of morality.
1. Social need. For social creatures to survive as social creatures there needs to be rules. With out rules any social system will collapse.
2. Instinctual. All social creatures (and even solitary creatures (and even solitary creatures) have rules and these rules are instinctual. A pack of wolf's/dogs has rules and the rules remain the same if the pack was raised by humans, Chimpanzees have rules to there troupes, Lions have rules to there prides, Dolphins have rules to there pods and these rules are instinctually based.
3. Emotional. Humans are born with empathy, compassion and a conscience. We feel for others, when something bad happens to some one we feel bad for them, when we do something wrong we feel guilt.
4. The deal. A simple unwritten, unspoken deal that every one agrees to. Don't do bad stuff to me and I will not do bad stuff to you.
4 simple securer, non god based logical sources for morality. Of corse these do not tell us what is moral and immoral but they give us the framework categorizing things as morel, immoral and gray (nether).
What makes the the statement worse is that theism tends to corrupt morality. 9/11, the inquisition, the crusades, Islamic fundamentalist terrorism, animal and human sacrifice, wars fought between Protestants and Catholics, wars fought between Christians and Muslims, wars fought between Muslim and Hindus, wars fought by Christians, Muslims and Jews against Pagans, oppression of minority religions, oppression of religions that are not blah religion.
By putting your morality in the hands of a god, what ever you think that god wants becomes morally right and what you think god dislikes, doesn't want or just declare wrong becomes morally wrong. What it is doesn't matter, it could be impaling baby's, roasting them and eating them, if that's what you think God wants than that morally right.
