You are confused. Unless you are a moral relatavist, stating a moral claim is ALWAYS fightin words. That’s because in any system of absolute right and wrong, all moral claims must occupy the same space.
Hobbes thought, as you seem to, that morality was just a synonym for “my opinion about what I like and I don’t like.”
Hume corrected this view, pointing out that, well, it MIGHT well be that morality ultimately boils down into that, but the fact is, when people express something that they call a moral, they MEAN something more than that, utterly regardless of whether they can really support it via some ultimate, incontestable metaethic. To express it as a moral means that they think, at least in principle, that they can. So when someone says that something is wrong, they aren’t trying to merely express an opinion: they are, in effect and BY DEFINITION, expressing the expectation that you and everyone else agree with them.
And if they/you aren’t, then we just aren’t really talking about morality in the first place, we’re just talking about taste and appreciation.
Maybe you are just expressing a matter of taste. In which case, I have no dispute with you, but then you also might want to rethink the use of words like sin and wrong, and so on.
It’s just too bad that your scope of things that you can appreciate and enjoy is artificially limited by something as trivial and mutable as taste. (I used to hate country music, but then I realized that I had nothing to lose, and everything to gain, from learning to like it, and so I did so, and now the world contains even more things that I can enjoy and appreciate)
Uh, nothing. It isn’t wrong to attack a faulty morality, per se. The question is: who’s morality is faulty? We both think the other fellow’s is, and so we both see their expression, as well as their counterattacks, as morally illegitimate. And though we can’t both be right, it is possible that we’re both wrong.
