The moral assertion is 'slavery is morally wrong'. And that assertion expresses a value-judgement, and is therefore subjective.
Well, you're just dogmatically re-restating your previous claim. "Slavery is morally wrong" does not NECESSARILY express a value judgment. It may also express the fact that slavery is inconsistent with some moral goal, in the same way that ""You're going the wrong way" means the traveler's current path will not get him where he wants to go. And, yes, the claim is
morally wrong if the goal in question is a moral one.
I agree that expressions of moral judgment can express no more than personal sentiments and values, conditioned responses, regurgitation of thoughtlessly accepted dogmas. When they do they are indeed subjective. And non-rational. But as philosophers we are interested in a
rational basis for moral judgments.
When a philosopher declares, "X is morally wrong," he is not voicing a personal sentiment. He is saying that X is inconsistent with the theorems of a coherent, consistent, rationally defensible moral theory.
But 'slavery is contrary to some accepted or postulated moral goal or axiom' is not a moral assertion. It's a factual assertion.
Indeed it is. Rationally defensible moral judgments ARE factual assertions.
It may well be objective and true, but it doesn't make any moral claim, such as 'it is morally wrong to act in a way contrary to some accepted moral goal or axiom'.
That sentence is incomplete. Did you mean to add "true" to the end?
If so, of course it is true,
by definition. "X is morally wrong"
just means, "X is inconsistent with a sound moral theory." It doesn't mean, "I don't like X."
You seem unable to get past your entrenched conception of morality as merely an inchoate hodgepodge of personal sentiments. You apparently
define "morality" as consisting of subjective feelings and values. And, of course, if you define it that way, then a rational morality is not just impossible, but nonsensical.
So stop defining it that way.
