"Vicarious redemption of sin is one of the most bankrupt moral constructs ever..."

Why claim that?

And I mean that question in the sense of modern principles of ethics, as I see not a speck of scientific evidence for the existence of any god(s).

Look at Baptists and Anglicans and Lutherans and Catholics.

Are their leaders telling them that they are responsible for the decisions they make? Yes. Are their leaders telling them that it is a grave wrong to do "bad" actions? Yes. Are their leaders telling them that it is important to work at resisting temptation to do "bad" actions? Yes. Are their leaders telling them that their god expects them to resist temptation to do "bad" actions? Yes. Are their leaders telling them they risk severe, permanent penalty because of bad actions inherent in humanity? Yes.

So where is moral bankruptcy in adopting some grand being as a great forgiver, be it a mighty tree-god or sun-god or whatever? Such a belief actually seem silent, in ethical impact.
