"The ten commandments are not corrupt in anyway"

What exactly do you mean by this? Can you define "corrupt" as you've used it here?

I would argue that ethics do not derive from religion. I would argue that ethics are ingrained somewhere deeper and more primal within man's mind and therefore influence religion. You will be hard pressed to find a religion anywhere that takes itself seriously and pushes messages such as "harm everyone you can" or "do as you please, the hell with any consequences" exclusively. Native American socieities operate on roughly the same fundamentals (don't kill people just for the hell of it, that's bad...help your family...that's good) and yet their religions are rather sparse and quite diverse. They definitely did not have a thing to do with the ten commandments.

I know this example violates your rule of not wanting a response charged with examples from -other religions-, but then again I'm not sure what the focus of your arugment is. "What good have atheists ever done us?" I'm not sure what you're asking; I suppose that that is the impression I get. If so, I would say that if atheists have done anything for society in terms of ethics, it's simply that by existing and by not becoming hideous degenerate murderers, they generally quell the misconception that no religion means no ethics. It may not be a mind-blowing revelation, but it's something.
