Frank,
I respond because I'm the moderator and I see all of the posts.
When I say that empathy is hard wired, I mean it's part of how our (normal) brains are wired. There are many people who are born without empathy. They are generally considered sociopaths. And is is possible to damage someone to the point where they lack empathy. I'm thinking of children in some African countries who get swept up into the war and made into killers.
My point is that morality has some objective basis -- in our evolutionary past. It is true, too, that what we call morality is also influenced by culture (including knowledge).
We define our atheism as a lack of belief because we can make definite statements about our own beliefs, but we can't prove a universal negative: that there is no god anywhere in the universe. I'm sorry if the definition bothers you.
What, specifically, would you like research for? If you've already decided that us guys at the ACA recycle bullshit, why should I waste my time responding to you?
