The above post is confusing normative ethics with metaethics. Metaethics talks about the nature of ethical facts. Normative ethics is how we know what is good. Thin realism argues we don't need to have a metaethical nature underlining it. However, even non-realists can treat ethical facts as conventionally true but not refelcting some metaphysical truth. Buddhism is a good example of this , it has a very develoepd normative ethical theory but because of their metaphysical claims tend to entail that view, although they sometimes take an intuitionist or naturalist account at a different level.
