what are we supposed to say again when christians ask us where we get our morality?

[Rampant.A.I.]

I get my morals from my empathy and my compassion for my fellow man.

I believe that man has a biological and evolutionary imperative to help one another.

I believe that man evolved his sense of family and empathy as part of our survival in a harsh world. Had all humans been sociopathic loners, we'd have died off many millennia ago. Only by sticking together and forming communities did we overcome the myriad of obstacles. Therefore, compassion and empathy are hard wired in most people.

That is where I feel we get our morals from.

That's really just another way of saying "might makes right."

So I guess when cockroaches scurry into dark corners they are acting as moral agents? After all an evolved adaptation is an adaptation. What is the difference between human empathy and the cockroaches instinct to flee?

Actually it's the opposite of might makes right, because sociopathy is seen as abnormal and requiring control.

The cockroach comparison is an insipid equivocation, as no one has claimed cockroaches have developed society complex enough to require moral codes, and the only reason to make such a comparison would be out of a knee-jerk reaction.

A moral code is not the same thing as an instinct. There seems to be an instinctual impression of right and wrong, but finer distinctions seem to be cultural.

You're also conflating moral agents with empathy, congratulations on the strawman.
