"And frankly, it's kind of offensive when Christians tell me I'm less-than-moral because I don't need their scripture to decide what's good or bad."

The moral argument isn't telling you that. You people (HN readers) seem intent on misunderstanding my initial statements.

It's not that atheists are not moral. Not even less moral than religious people.

The point I am trying, and failing, to express is that morality must come from a higher, non-human source. If it does not, then it is just a product of fallible human minds and is entirely meaningless. That's it.
