The fact that morality is relative is made obvious even by Christian doctrine, which draws lines between things like the genocides their god is alleged to have committed, and the genocides they're happy to deprecate.
They're all too happy to mention the millions killed by Stalin as "evidence" that atheism leads to immorality, but refuse to consider the billions their god has killed as evidence of the same. But the fact that the morality of those genocides is relative to 1) who commits them and 2) who is victimized by them is evidence, in the behavior of the very same Christians touting moral absolutism, that morality is relative.
Sucks to be them.
