Personally, I'm Christian, and the bible says not to have contention which =arguing,
so I stay out of that...as much as I can, and I do pray about any 'argument' that
I get into at all. It needs to have some value for me to feel right about getting into one.
Some people argue for all the reasons listed by others here. I might counter
something because I don't want to see God maligned, or because I think
the person could be searching and needs to see their viewpoint differently.
Have you EVER had someone argue you out of your own viewpoint in other
areas? I have had this done and seen I didn't hold the better view. I dropped
my view....on other things, not God. So some people WILL make changes
as they read 'arguments' IF the person is looking for something like that.
