morality is subjective and people don't have free will

[Angrboda]

If you want to posit the non-physical as an explanation, go out and find me this non-physical.

This demand begs the question. What we call physical is inferred from intellect and experience. Someone must rely on intellectual objects in order to posit physical objects on which intellectual objects can supervene. Seems circular unless I'm misunderstanding your point about SteveII's appeal.

I don't have the foggiest what you're on about. If asking for evidence and a model of the non-physical before it is accepted as an explanation is begging the question, well then I'll gladly beg the question.
