Subjective Morals and Societal Whims

[Silver]

I like to see your source because it sounds like you pulled that straight out of your backside. Not even animals make a habit of killing thier own species for no reason.

It's an anthropologically sound study.

It simply stakes a google search.

What's an atheists metric for determining what qualifies as good?

I figure it follows along the lines of ensuring no harm comes to another.

Theists were in favor of slavery, which harmed others.
Theists were in favor of burning witches, which harmed others.
Theists were in favor of plenty of things that harmed others, all in accordance with the bible and the god in which they believed.
