You are still requested to explain why having a cohesive society is a moral aim which you imply it is.
And then, to back up this claim, you produce a large quote. Yet the quote only explains the difference between the two, not where they overlap.

I've never made any claim about any heirachy of value regarding descriptive and normative value. I am simply arguing that they are different things and yet you keep confusing them.
A descriptive account of the differences between cricket and baseball need not imply that one is better than the other, and I would argue that descriptive accounts of morality, either from the point of view of how human beings make moral choices or comparative anthropological studies of the morality of different societies (perfectly scientific and worthy endeavours in their own right), are different from normative issues on what people ought to do.
Yes, but clearly in the example I am giving we are not really talking about mutual co-operation. We are talking about using people for our own ends and furthermore relegating certain creatures such as animals, or even future generations of humans to not even being worth considering.
But now you are imbuing this scenario with two things:
a) first, you have an unsupported claim that this behaviour is "immoral". On what grounds? Why should "selfish" behaviour be considered "immoral" when from the point of view of the person engaging in it, it's really really great! No deus ex machinas please
and
b) your second sentence can only be judged
wishful thinking. It is most certainly not a scientific claim and there is no such thing as cosmic justice. I am sure there are many of us who would like to see Bad people punished, but we really need some account of what Bad is, and that, is exactly what normative ethics is about deciding. However, as much as it can be informed by science regarding what effects some person's behaviour may have, science cannot tell me that it is Bad. For example, when did society rise up against Chinghis Khan or Stalin? We can agree that these people are Bad but the laws of nature do not conspire against them like some Cosmic Judge. As Nietzsche pointed out the universe is indifferent, and as Dawkins said:
That's okay, you only have to admit that you got the numbers of genes wrong. I would respect an honest admission.
Thanks for the link, but now I am a little confused. You have argued, I think, that there is no such thing as objective morality, and also that there is no such thing as something which is "moral in and of itself". Does Dr Carrier who you appear to be citing with approval here, agree with you?
I was actually hoping you would give me your synopsis of Dr Carrier's argument actually because you argued that he had written on the same topic in The End of Christianity. Do you have that book and/or have you read this chapter from him?
That's a rather ironic farrago.
