My meta-ethics are basically that of Luke's Pluralistic Moral Reductionism. (UPDATE: Elaborated in my Meta-ethics FAQ.)
However, I was curious as to whether this "Pluralistic Moral Reductionism" counts as moral realism or anti-realism. Luke's essay says it depends on what I mean by "moral realism". I see moral realism as broken down into three separate axes:
There's success theory, the part that I accept, which states that moral statements like "murder is wrong" do successfully refer to something real (in this case, a particular moral standard, like utilitarianism -- "murder is wrong" refers to "murder does not maximize happiness").
There's unitary theory, which I reject, that states there is only one "true" moral standard rather than hundreds of possible ones.
And then there's absolutism theory, which I reject, that states that the one true morality is rationally binding.
I don't know how many moral realists are on LessWrong, but I have a few questions for people who accept moral realism, especially unitary theory or absolutism theory. These are "generally seeking understanding and opposing points of view" kind of questions, not stumper questions designed to disprove or anything. While I'm doing some more reading on the topic, if you're into moral realism, you could help me out by sharing your perspective.

Why is there only one particular morality?
This goes right to the core of unitary theory -- that there is only one true theory of morality. But I must admit I'm dumbfounded at how any one particular theory of morality could be "the one true one", except in so far as someone personally chooses that theory over others based on preferences and desires.
So why is there only one particular morality? And what is the one true theory of morality? What makes this theory the one true one rather than others? How do we know there is only one particular theory? What's inadequate about all the other candidates?
~
Where does morality come from?
This gets me a bit more background knowledge, but what is the ontology of morality? Some concepts of moral realism have an idea of a "moral realm", while others reject this as needlessly queer and spooky. But essentially, what is grounding morality? Are moral facts contingent; could morality have been different? Is it possible to make it different in the future?
~
Why should we care about (your) morality?
I see rationality as talking about what best satisfies your pre-existing desires. But it's entirely possible that morality isn't desirable by someone at all. While I hope that society is prepared to coerce them into moral behavior (either through social or legal force), I don't think that their immoral behavior is necessarily irrational. And on some accounts, morality is independent of desire but still has rational force.
How does morality get it's ability to be rationally binding? If the very definition of "rationality" includes being moral, is that mere wordplay? Why should we accept this definition of rationality and not a different one?
I look forward to engaging in diologue with some moral realists. Same with moral anti-realists, I guess. After all, if moral realism is true, I want to know.
I will answer by explaining my view of morally realist ethics.
Conscious experiences and their content are physical occurrences and real. They can vary from the world they represent, but they are still real occurrences. Their reality can be known with the highest possible certainty, above all else, including physics, because they are immediately and directly accessible, while the external world is accessible indirectly.
Unlike the physical world, it seems that physical conscious perceptions can theoretically be anything. The content of conscious perceptions could, with the right technology, be controlled, as in a virtual world, and made to be anything, even things that differ from the external physical world. While the physical world has no ethical value except from conscious perceptions, conscious perceptions can be ethical value, and only by being good or bad conscious perceptions, or feelings. This seems to be so by definition, because ethical value is being good or bad.
That a conscious experience can be a good or bad physical occurrence is also a reality which can be felt and known with the highest possible certainty. This makes it rational, and an imperative, to follow it and care about it, to act in order to foster good conscious feelings and to prevent bad conscious feelings, because it is logical that this will make the universe better. This is acting ethically. Not acting accordingly is irrational and mistaken. Ethics is about realizing valuable states.
Human beings have primitive emotional and instinctive motivations that are not guided by intelligence and rationality. These primitive motivations can take control of human minds and make them act in irrational and unintelligent ways. Although human beings may consider it good to act according to their primitive motivations in cases in which they conflict with acting ethically, this would be an irrational and mistaken decision.
When primitive motivations conflict with human intelligent reason, these two could be thought of as two different agents inside one mind, with differing motivations. Intelligent reason does not always prevail, because primitive motivations have strong control of behavior. However, it would be rational and intelligent for intelligent reason to always take the ultimate control of behavior if it could somehow suppress the power of primitive motivations. This might be done by somehow strengthening human intelligent reason and its control of motivations.
Actions which foster good conscious feelings and prevent bad conscious feelings need not do so in the short-term. Many effective actions tend to do so only in the long-term. Likewise, such actions need not do so directly; many effective actions only do so indirectly. Often it is rational to act if it is probable that it will be ethically positive eventually.
That people have personal identities is false; they are mere parts of the universe. This is clear upon advanced philosophical analysis, but can be hard to understand for those who haven't thought much about it. An objective and impersonal perspective is called for. For this reason it is rational for all beings to 'act ethically' not only for themselves but also for all other beings in the same universe. For an explanation of why personal identities don't exist, what is relevant for the question of why acting ethically in a collective rather than selfish sense, see this brief essay:
