The biggest problem I have with this is the idea that morality, and the idea of social responsibility
has to come form an external source, be it a belief in God, the belief that if you don't do these things you'll go to hell, or whatever. This implies that we, as a species
fail at being social animals. That without these things, we'd all turn into little Ayn Rand objectivists and society would crumble as it stands.
So let me ask you this question: Do Wolves, ants, bees, or rabbits believe in God or an afterlife? These are all social animals, some of them having a very complex social structure, and all of which have demonstrated a fundamental grasp of the "greater good." Does that make them better than us because they don't need an external force to constantly reinforce the idea that if you look out for your kin, your society, as a whole, benefits?
Here's another thought to chew on: I contend, that as an Athiest, I have a stronger sense of morality than a Theist. Here's why. I don't believe in an afterlife. I believe that this is it. This is the only life we get. A theist could rationalize murder becuase, while their own soul may be damned, at least their victim could live in eternal peace. An athiest couldn't because to murder would be to condemn somebody to the void. It makes life
more valuable because this is the only one we've got.
Okay. Done trollin'
