Athiest don't even employ reason. A quick perusal of the combox of this article is enough to establish that. They babble about morality, but have no basis for it. They speak of culpability while failing to see that the end of thier argument is completely deterministic. I oppose athiesm not because I think it violates a transcendant morality based in God, but because the chemicals firing my synapses are responding to stimuli that force me to think as I do. So naturally I must have defective reason, which is impeding the upward evolution of the species. Guess what comes next.
