Is it true that there is no absolute morality?

[Neo-Scholastic]

The Ethiops say that their gods are flat-nosed and black,
While the Thracians say that theirs have blue eyes and red hair.
Yet if cattle or horses or lions had hands and could draw,
And could sculpt like men, then the horses would draw their gods
Like horses, and cattle like cattle; and each they would shape
Bodies of gods in the likeness, each kind, of their own.

-Xenophanes c.500BC

You do realize that Xenophane was arguing for a more austere and comprehensive monotheism. This was his critique of the popular polytheism of his time. How typical of you to present an uneducated argument of convenience that actually means the opposite of what you think it does.
