I'm not going to get sucked into this, as it would amount to a super-derail, with the locomotive upside down and wagons everywhere. But as a starting point, would you not agree that murder and rape are objectively wrong rather than a matter of opinion ("Subjective, adjective, based on or influenced by personal feelings, tastes, or opinions")?
Pretty much every theory of morality that has ever been advanced (deontological systems, Kant's categorical imperative, consequentialism, the current fashion, virtue theory (though I don't really understand it)) assert that certain actions are definitively right or wrong.
Pacificdogwood, apologies if I took offence unnecessarily. I always feel a bit on the defensive for some reason
