I tend to think God has a sense of humor and is looking down on all you saying, "I'm right, you're wrong".... "No I'm right, you're going to Hell"... over the different intrepretations of writings in a couple of books.
At least I hope He has a sense of humor... otherwise, upon croaking, there are going to be a lot of very surprised people.
As a general We Christians get along just fine thanks. There is far more we agree on than not and one thing we agree on officially is the LDS is outside of the family.
