This word is thrown around a lot here, from what I can tell by a group of Atheists(?). I am shocked and surprised to see people discussing some numinous, universal non-religious morality. When I was in college 10000 years ago, "moral relativism" was all the rage.

Can someone clue me in as to EXACTLY what moral system you are all referring to? What's its genesis, to whom does it apply, from where arises its rights and duties regarding strangers?

From what I can see it is now considered "immoral" to do things that just might not be very nice.
