I don't see how those three exclude Moral Non-Naturalism. Certainly, the majority of divisions I've seen have put MN-N as a form of Moral Realism...

I think Robb's intention was to say that moral non-naturalism, universalism, and primitivism are all species of the moral-realist genus, but that one can be a moral realist without being any of those three (as EY is, I believe).

Could be. Re-reading the comment hasn't helped me clear up my confusion, so maybe RobBB can clarify this for us.

My intent was just to highlight that realism, non-naturalism, universalism, and primitivism are different ideas. I wasn't weighing in on their relationship, beyond their non-identity. Universalism and primitivism, for instance, I'd usually consider compatible with an error theory of morality (and thus with anti-realism): Moral statements are semantically irreducible or structurally applicable to everyone, but fail to meet their truth-conditions. Similarly, I could imagine people committed to anti-realism precisely because moral facts would have to be non-natural. We may not want to call the latter view 'moral non-naturalism,' though.
