CC: if someone made a statement on here that was offensive to Muslims or defamed Mohammed, this group would be on them like bees on honey.
Likewise, the unnecessary use of God's name is offensive to Christians. One of the 10 Commandments says in Exodus 20:7: "You shall not misuse the name of the LORD your God, for the LORD will not hold anyone guiltless who misuses his name". "Misuse" is a different translation of the more commonly heard "Thou shalt not use the name of the Lord your God in vain..." where "vain" would have the meaning of "cursing in anger" or "unnecessary use".
So you can keep saying it, but just because you're not religious does not mean that you're not being offensive
. I am not Muslim, but I show enough respect for Muslim human beings to not intentionally offend them.
So, I agree with Flybye...
As for OMG, I prefer to think of that meaning "Oh My Gosh"...because the alternative makes me think of the disgusting inflection that Moon Unit Zappa gave it in "Valley Girl"
