Rhi,
Do I need to justify myself to you? I don't think so.
Of course not. If anything, I'd have thought it was for Trollboy finally to justify his assertion about the supposed logical contradictions in moral relativism (with or without reference to claims of objective morality) but that never quite managed to make an actual argument for.
While he's about it, he might want to explain too why all those moral philosophers who weren't objectivists were wasting their time as (he tells us) moral relativism has nothing to say about "real" morality, and for that matter perhaps he could share why he arbitrarily separates morality for this purpose but seems quite happy for people to hold legitimate but differing opinions on painting and music and literature and indeed on countless other areas of human experience.
I suggest you don't hold your breath though!
