We're not talking about "one set of morals", Nancy. That phrase still contains relativistic connotations. We're talking about the only set of morals. Logically arrived at morality is the only morality. It is objective morality.
We may all have different ideas about complex moral questions, but that doesn't mean that we're "all right", and conversely it doesn't necessarily mean ANY of us are right. Once again, if you and I come up with a different answer to a complex moral question, it doesn't mean that "both our answers are valid". It means one or BOTH of us is wrong. Plain and simple.
