What's wrong with having morals that are based in a religion? Even if one isn't of one of the Abrahamic religions, one can still subscribe to the Ten Commandments and follow them. Just because some morals are based around a religious faith doesn't mean that all morals are, and it certainly doesn't mean that the ones that are based in religion are bad.
So you're saying we should ignore the 10 commandments just because they're religious based? I'd hate to be your kids. "My daddy says I don't have to follow the 10 commandments so Imma gonna kill me some people, treat my parents like crap, cheat on my wife, steal me some things, lie my ass off about it when I'm caught, and I'll live in a constant state of jealousy of what every one else has. But it's okay because daddy says that religious morals suck." *waits for impending lethal injection*
You're both idiots for assuming that ethical behavior cannot exist without religion. It's funny how you only mentioned the commandments that actually have a purpose. I'd rather my children never follow this list of handicapation:
The Ten Commandments (Exodus 20:2-17 NKJV)
1 “I am the Lord your God, who brought you out of the land of Egypt, out of the house of bondage. You shall have no other gods before Me.
2 “You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; you shall not bow down to them nor serve them. For I, the Lord your God, am a jealous God, visiting the iniquity of the fathers on the children to the third and fourth generations of those who hate Me, but showing mercy to thousands, to those who love Me and keep My Commandments.
3 “You shall not take the name of the Lord your God in vain, for the Lord will not hold him guiltless who takes His name in vain.
4 “Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the Lord your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates. For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the Lord blessed the Sabbath day and hallowed it.
I think we could all do without that. This list is in fact harmful because it equates the pointless rules above with murder, rape, adultery, and theft.
