It entirely depends on how you define morality as to if there is an objective truth to it or not.Either you believe there is an objective truth to morality and therefore lack wisdom, or you accept there is no objective truth and lack humility. I wonder which one it is?
If you assign variables which can be measured then yes it is, if you don't then no - it isn't.
My point was you believing in hanging children which in my view is a good indicator of dysfunctional mind (ergo being wrong about most things).
