I'm an Atheist, but some aspects of the 10 Commandments are common sense.
Respect your parents: I'm okay with that, as long as they aren't a couple of criminal douchebags.
Don't steal. I don't want my stuff stolen and want those that steal punished. I worked for what little I have.
Don't kill: I don't want to be killed, so I don't want people murdered that aren't murdering scumbags.
Don't commit adultery: I wouldn't want my significant other having sex with someone else and wouldn't be unfaithful to her.
So, I can get onboard with four of the ten. The others, I don't care much about.
