Are all societies and cultures morally equal?

[William F. Owen]

While it's true there are a few foundations that almost all humans believe are wrong, they are still highly variable and dependent upon circumstance.

Very well aware. However there are basics on which most of the world's major religions have broad agreement on. Are these effected by context? Sure, but don't confuse actual morality with the cultural or social context in which it is applied, - thus the question - Are all societies and cultures morally equal? - that's something different from the moral norms common to most religions.
