The moral argument for God is very convincing to Internet apologists because they believe in something called transcendent morality. It comes up by many names including objective morality, absolute morality--and as I prefer, cosmic morality and magical morality. Regardless of the name, it is seen as a moral standard that exists somewhere independent of the minds of mere mortals and supersedes alternative judgements.
That’s the claim. Is there proof? No. Is there evidence? No. The defense for the claim is essentially finding a moral value agreed upon between the apologist and the non-apologist, such as “murder is wrong,” and using that shared common ground to say all other assessments aren’t just wrong from their perspective, but wrong independent of perspective.
What do you think, is murder wrong independent of perspective? In my experience, “wrong” means different things to different people. It is like saying not murdering is better than murdering. “Better,” like “wrong” in this case, is imprecise language that the apologist can leverage during these exchanges. Analogy time. What if I said lemons are an objectively better fruit than blueberries? This seems laughable because we understand taste preferences are opinions. However, we can say something is objectively true here if only I use a clear metric. I value sour flavor. Lemons are objectively more sour than blueberries. This isn’t a matter of taste, we can actually compare pH levels and know for a fact that lemons are more sour and are therefore objectively more appealing to one who values sour flavor.
Apply this to morality. Instead of saying something imprecise like not murdering is better than murdering, which could be subjective or objective depending on the metric used to judge something as “better,” let’s say not murdering allows for a safer world than murdering. This specification allows us to say not murdering is better for those who value safety. That is an objective fact and an instance of an objective moral.
I cannot say anything about one’s morality without saying something about one’s values. Because the majority of us value human life, safety, and equality (at least to some degree) the discouragement of murder is near universal...but transcendent? No, that is neither justified nor demonstrable.
