Since it's getting off topic in more than one thread, I'm going to bring the argument out here.
Sin is a separate concept from "right and wrong".
what is sin? breaking god's law. it is a religious concept.
what is "right and wrong". depends. generally, wrong is stealing. right is holding the door open for someone right behind you.
"right and wrong" can also be related to secular law. in other words, the law that tells you, if you murder someone, and we can prove your guilt, you have to serve x.
now then, removing sin from "right and wrong" does not lead to moral bankruptcy. it does not lead to gas chambers, hitler, rapists, murderers, or anyone else or thing missing the concept of morality or "right and wrong".
Also, Rob, I will not allow anyone to state that I approve of Hitler's actions because I do not accept the concept of sin as being part of "right and wrong". it is a straw man, and an insult to who I am. Also, bringing up Hitler's "final solution" is a strawman.
let the argument begin.
(oh, and this is not meant for a Great Debate)
