The Debate Between Objective Morality and Moral Relativity Intensifies
This would be far more convincing if you backed your opinion with evidence of your opinion having a shred of credibility.
Objective morality does not require consensus any more than objective science requires consensus. It also does not require the correct permutation of cosmology as the incorrect cosmologies are by definition not the correct cosmology. It does require verifiable results.
Your analogy to personal taste as regards “best ice cream” is actually far less serviceable than the morality of any organized religion and the decline of society as produced by post-modernism and Marxism (that is likely redundant) is a demonstration of moral relativity’s failure
I’m not sure what you are on about. If I think that someone has objective morality correct why would I disagree with them? And in what way would that prove or disprove my point? Everyone likely does have a different perspective on objective morality, moreover…
… their perspective likely changes as they age and accumulate more personal experience. This still does not negate the concept of objective morality. What is demonstrably fraught with inconsistency is moral relativism. Hitler probably thought he was acting morally.
The measure is to see what has worked historically through the ages to promote a peaceful and productive society. It’s not complicated. There are innumerable sociological and psychological studies that demonstrate what sort of human behavior is most conducive to healthy people.
You can look at the success of Western Civilization in promoting safe and prosperous societies around the globe. Western Civilization is a balance of Greek philosophy and Judeo-Christian ethics and wisdom. None of this is debatable.
In comparison, embrace of Marxism and post-modernist ideology has demonstrated decline of society, education, family, art and philosophy. So you then compare the rules of the two models and ascertain which demonstrates a better outcome.
Now if you want to argue about what constitutes a better outcome and thus question the validity of objective morality in that way, have at it, but it’s fairly universal to believe that the best outcome is a peaceful and prosperous society. This is extraordinarily well documented
