I don't think you can explicate such a connection, especially not without any terms defined. In fact, it is just utterly pointless to try to develop a theory in a field that hasn't even been defined in a coherent way. It's not like it's close to being defined, either.

For example, "Is abortion morally wrong?" combines about 12 possible questions into it because it has a least that many interpretations. Choose one, then we can study that. I just can't see how otherwise rationality-oriented people can put up with such extreme vagueness. There is almost zero actual communication happening in this thread in the sense of actually expressing which interpretation of moral language anyone is taking. And once that starts happening it will cover way too many topics to ever reach a resolution. We're simply going to have to stop compressing all these disparate-but-subtly-related concepts into a single field, taboo all the moralist language, and hug some queries (if any important ones actually remain).
