I suspect what you're really looking for is a moral realist who frames all of their moral statements in all/non fashion (all murder is wrong; lying is never right) and I will be of less use to you on that front.
No, why would I? The simple assumption of universal moral truths is all I require. It is easer to argue them when they are absolute in their truth, but a nuanced truth can just as well be argued with the possibility of an absolute moral value which contradicts the nuanced supposed "truth".
For instance, what makes the notion that murder is usually wrong any more true than the notion that murder is always wrong or never wrong? I just don't see a sensible basis for this at all to be blunt. Just as I see no sensible basis to argue that me hating raisins is a universal emotional truth and others were
wrong to not hate raisins.
For reference, I would consider myself a meta-ethical relativist, but not a normative relativist.
Yeah, me too. I feel like people who conclude from meta-ethical to normative relativism didn't get relativism to begin with (edit: or as it turns out -
I didn't get what moral relativism means

). Because its central message is I as I understand not that all moral beliefs are equally good or bad, it is that good or bad is not truth but opinion.

Thanks for the links

But if I wanted to read endless essays about moral philosophy to see why so many philosophers disagree with moral relativism I would read endless essays instead of posting on OT. Too bad you don't feel qualified. I don't want to do so especially because for me the issue is actually pretty simple so that I don't see it warranted to read endless essays.
Moral relativism is entirely separate from cultural relativism. It is used as an insult because it is conflated with cultural relativism, sometimes used as an excuse for cultural relativism, and because it conflicts with religious and philosophical dogma about objective morality, which upsets people wedded to such beliefs.
Thumps for this post
@lovett
Oh, so I didn't actually know what moral relativism means I guess? Moral relativism also assumes moral facts?
Oh well, then I guess I am in deed a moral skeptic instead of a relativist.
So while relativism means that morals are relative, this does not mean they are arbitrary.
Yeah according to what lovett says it absolutely does not, my mistake. Thread screwed up - but I learned something!
Sounds more like
subjectivism (Stanford Encyc. Phil. link) than relativism per se.
More, true, but from reading the link moral subjectivists still assume the existence of moral truths, just depending on the mind rather than a setting as in moral relativism.
I think moral truth only exists
within a frame of reference which is based on a defined set of premises and is logically coherent. If one subjectively agrees with the premises or conclusions doesn't enter the equation.
What is a "source" and why does objectivity require one?
A source is the necessity of existence. Just thought that up, but it rings true.
Something that objectively exists requires an objective source to be verified in its existence. For instance - a stone objectively exists because we an verify its existence by objective gadgets such as sight and touch (or rather, by gadgets we assume to have an objective quality because otherwise we couldn't make any sense of anything but so we can make a lot of sense of a lot of things in very useful ways). Here source of the stone is its physical body (or chemical and actually physical processes).
Is a source more than just a subject-matter?
I don't understand this question.
What is the "source" (if any) of objectivity in logic?
It corresponds with the causal relationships which shape our world and our minds.
See above.
That depends I would say. It is certainly possible to argue something in that field which is pure arbitrary subjective nonsense.
In any of the natural sciences?
See the stone-illustration.
Now, what exactly is the point you are trying to make? Because as you may guess - I am not really seeing it.
