Eliezer, was your previous thread "Your Rationality is My Business" about moral judgments or factual beliefs? It seems you want to discuss the nature of morality WITHOUT discussing more "elementary" assumptions about our relationships to "reality" or "the world at large" or "the universe", etc... Even the wording above is controversial and a matter of debate. Sweeping these questions "under the rug" is surely not the way to clarify the discussion about "morality" and reach any kind of consensus. Most especially if you pretend to have a special right to oversee other people thinking. Cheap arguments cannot be used to justify "thought police".
