Did you read and get my explanation that a “concept of God” is independent of his existence and independent of the necessity of His existence for such a “golden rule” to exist and be universal?
Yes, I read it. I just didn't think it was relevant to the discussion at hand, which was about belief in God and the codification of God's laws being necessary for morality. From a non-believer's perspective, the golden rule does exist and is universal, they would just disagree on the "why" that is so. But if you believe I'm missing a subtlety I'll listen.
