Sure, there are plenty of moral relativists here; but given that Eliezer's metaethics sequence explicitly contrasts itself with traditional moral relativism and that Luke's moral reductionism sequence holds out several levels of the objective-subjective distinction (to each of which moral relativism gives the subjective answer) as open questions (pending the rest of the sequence), I'd say that the Less Wrong consensus is "reject naive moral realism" rather than "embrace moral relativism".
