Isn't this basically the Companions in Guilt argument, a la Cuneo? As go moral facts, so go epistemic, hence the anti-realist's argument is self-defeating. But I think epistemic normativity, at least w.r.t. the mundane physical world, can be grounded in my desire (i.e. my stance) to navigate that world in a way promotes pleasure over pain. And I suspect (not that I've worked it out ;-) that that can be extended to more abstract domains. Moral normativity would be grounded in our common (with some exceptions) desire to live in a peaceable, orderly social environment, which to me gestures in the direction of some variety of contractarianism.

And this "If the other guy doesn't care about breaking the law, then he's right to murder me, and I have no valid objections" strikes me as just plain weird. Even if we accept that kind of relativism, my dying violently is against *my* value system, which gives me the right to resist by all means available.

I agree with the thrust of this post, but I suppose in the spirit of candor, one could be more charitable to the realists here and suggest that their objections isn't a failure to imagine the antirealist position, but rather an appeal to an impulse they infer others have. Presumably they believe others to feel a particularly different feeling upon apprehending moral arguments from arguments about descriptive facts.

That's how I understand the discursive argument offered in the initial examples; they're suggesting it's odd to treat moral disagreements with any stridency or strong personal convictions if there's nothing unique about disagreeing on those facts that doesn't apply to disagreements about the effects of gravity.

I understand an antirealist response to this could simply be that people's dispositions vary internally and with respect to each other, and that their dispositions being different for different contexts is an interesting descriptive fact about them, not probative on what properties normative facts have. But I could see how that's less obvious or appealing than "maybe the thing that feels special (to you) is special!"
