Where do atheists get their morality from?

[Red Celt]

It isn't about wishing. I'm a moral relativist, therefore I strongly reject your claims about the default position of atheism.

If you're a moral relativist than you AGREE with me. I'm saying moral relativism IS the atheistic position.

The problem with moral relativism is self-evident: That baby-punching is morally good in some possible world on moral relativism. And that's not a moral theory that babies want to be in. Or anybody if they happen to find themselves on the less favorable side.

The morality of social animals is based upon reciprocity. Actions have consequences. I'm not interested in possible worlds; they are a construct of metaphysics. In this world, punching babies has consequences... and those consequences aren't devolved between theism and atheism.
