Just to note too that - even if we took Trollboy's personal opinion as somehow magically an objective moral truth too, it would lead to all sorts of practical problems if he tried to apply it. What if, say, humankind was about to be wiped out by a terrible disease but we found an Amazonian tribe with the genetic make up to cure it, only we'd we have to kill every one of them to obtain it? What would be the morally correct thing to do so as to satisfy his, "The ultimate definition of what is Good is what promotes everyone's humanity and what is bad as that which reduces it" opinion in that case?
Or how about the morality of birth control or of abortion - does "everyone" extend to the not yet born too?
Sadly his big book of divine rules doesn't deal with nuance, so I guess he'd be back to his personal opinions again if ever he tried to apply his choice of mantra.
Oh well.
