Can objective morality exist in Atheism?

[tavarish]

The golden rule, although objective, does not apply solely to morality.

This golden rule, when applied to morality, is subjective,

Ok, so the golden rule is objective or is it not?? (we are not concerned with what else it applies to) It applies to morality?

this would be much easier if you could answer with a simple yes or no.

I think I wrote it pretty clearly. The golden rule, as an evolutionary mechanism, in its truest sense, is objective.

YES.

The only thing that's subjective is when the concept of morality is tacked onto it. Then it has to do more with social ideologies and coexistence rather than ultimate survivability.

Golden Rule = objective.
Morality based on the golden rule = subjective.

understand?
