The problem I see with that definition is that we are asking to judge an opinion without opinions without opinions the opinion doesn’t exist so still no objective morality is still hogwash as it’s still a oxymoron if you see morals with zero judgements then everything is newtral right and wrong doesn’t mean anything how do you measure the morals of slavery without personal feelings you can’t say religion is bad that’s a opinion you can’t say human suffering is bad that’s a opinion you can’t say human prosperity is good that’s a opinion nothing is inherently good or bad as those are opinions without opinions you can only say you are blind as even saying it’s newtral is a opinion granted newtral is a debatable point so even if objective morality exist I’d be the most useless consept ever
