Moral relativity

[Copernicus]

[ QUOTE ]

Morals are defined by the society you live in. There is no absolute standard that they follow. Most have developed in a particular society to be beneficial for the common good. When one society's morals differ enough from another's, war sometimes breaks out.

Add "All" as the first word for emphasis, and QFT.

The problem with the OP is that the answer can really never be "yes", even though I voted yes. The gotcha on the yes side is that a "valid moral system" that lives within and depends on a society that has a different "valid moral system" is rendered invalid by that dependency.
