Okay, I think I understand now, thanks for the explanation.
For what it’s worth, the “factual” versus “moral” contrast you are drawing seems to me to be a distinction without a difference. Both the moral realist and the moral non-realist are looking for “nonarbitrary” units of measurement, and an argument that a certain unit was nonarbitrary seems like it would probably be persuasive to both the realist and the non-realist.
Well, the moral realist just assumes there exist non-arbitrary units by faith, since moral realism implies non-arbitrariness. The non-realist believes no such thing. :)
