[On what scale are you basing this on? Why is it wrong and yours right?]
I think you misunderstood the context of my answer. I wasn't saying that one or the other morality was "wrong" (although such a case could be made), I was saying that your notion that if there's not an "objective source", then all moralities "have just as much value" is, itself, wrong.
There is a large body of prior discussion on this topic, going back many centuries. I'm not going to trivialize it by trying to sum it up in a few paragraphs. Hit any decent library or do some web-based research to come up to speed on some of it. Suffice to say that there are many potential foundations for morality other just "God", most of which do not result in the kind of vapid "all moralities are of equal value" relativism you presume must be the case.
