Well my proposition is that survival of the fittest is a way to prove objective moral value. The axiom is that the survivor is the fittest.

Having a Value Axiom proves that the conclusion is NOT an "objective moral value"
Its an evaluation based on the arbitrary axiomatic framework.
Mental frameworks always precede observables.
I don't think you can make any logical argument without an axiom. Nothing exists in a vacuum.
I'm not saying Axioms by themselves are illogical. Moral axioms cannot be derived from observables, thats all.
They're "good" or "bad" because of some arbitrary Moral claim, within a relativistic worldview.
