I haven't read or heard a single convincing argument for Moral Objectivism. One is that of convenience (so that moral statements can be logically evaluated leading to conflict resolution), which I immediately discarded (its inspiration seemingly fits the category of wishful thinking). Maybe I have missed an important argument, in which case I can't wait to know it.
Can someone provide or point to a neat outline of the arguments for and against Moral Objectivism and Moral Relativism? A filmed debate on the subject of meta-ethics would be a nice addition to any answer or comment.
If we can help it, let's stick with the terms "Moral Objectivism/Moral Relativism" without using the alternate "Realism/Non-Realism" so not to confuse the unfamiliar reader.
