But societies of people have always , and still are, killing each other for land, for amusement, for the 'greater good'. Who is to say that they are wrong to do this now or in the past. You and I might think it is absolutely abhorent, but that is our opinion.
So nobody can have anything other than a ‘mere’ opinion. Which you’re now stating in the manner of an objective fact.

You seem to be quite (understandably) upset regarding what you ‘merely in your opinion’ see as exploitation of women in the porn thread over in the Relationships forum, but by what you’ve posted here, you have to keep it to yourself. I can see why this would cause anguish. I feel your pain!
However…
I don’t understand why if morals need to be agreed by society, that counts as
mere agreement, as if morals somehow ‘ought’ to have a deeper, more solid reality? The process of society agreeing on morals is the sum total of their reality
but this is not reductive of the reality of morals. I am honestly fascinated in this thread at the constant use of deflationary, pejorative terminology when referring to the subjective aspect of morals.
Perhaps some of the problem comes from a feeling that we are somehow apart from reality, qualitatively different. So you (hovis I mean) refer to a greater, Other reality, in cosmic terms which you then place in opposition to ‘merely’ us. Yet I prefer a kind of ‘weak anthropological principle’ style shift of focus, or
change of aspect (as in Wittgenstein’s duck/rabbit picture) which emphasises the fact that we are here now, and avoids hidden metaphysical assumptions that in some way we ‘ought’ not to be here (or indeed ‘ought’ to be here). And just as this shift of emphasis allows us to accept our existence, so it also allows us to examine our mental flora and fauna without this strange ambiguity towards morals where we are fascinated yet torn by anxiety as we cannot explain them. Morals seem to be mental flowers that are highly regarded as a genera, with various species and subspecies of varying degrees of beauty, or they could be viewed as part of the music of human interaction.
To use a musical analogy, some people may be tone deaf but that doesn’t mean music doesn’t exist.
A line must be drawn. The concept of compassion, or that of empathy is found in all humans. Sexual sadists are perfectly aware of the fact that they’re causing pain; otherwise they wouldn’t be interested in doing what they do. I’m specifically bringing up sexual violence here because imo it most forcefully undermines the relativist viewpoint. Issues of consent are what temper relativism. Issues of consent also bring in the matter of when to intervene. Moral relativism must be found wanting
first (a priori I suppose) if it’s unable to give any reason to intervene when somebody’s being raped.
Which philosopher was it who pointed out that humans have this tendency to try to take arguments to infinity and thus nullify them? (Honest question… can’t remember now… was it Leibniz? Or not?)
Speaking more poetically, I feel that morals seem to appear out of the edges of the eyes of the mind, and only appear when the ‘seeing’ of intellectual analysis relaxes and looks more deeply ahead. It doesn’t mean that they have no reality. In a practical sense they could be treated as objects mostly behind our (metaphorical) ‘field of vision’ which we can only assess by ‘looking outwards’, ie in this metaphor by acting in the world.
There will always be a tension between the subjectivism with which we individually experience the world and form viewpoints, and the fact that we are able to imagine ourselves in somebody else’s place. This does not need to be regarded as a bad thing, just a thing that goes with creation of morality.
(There could be a corker of an essay to write on the psychological aspect of moral relativism, as regardless of the theory, in practice it often seems to be infused with self-loathing, or at least misanthropy).
