If you’re a person who dislikes confrontation, arguments are most likely not your thing. While most people don’t really like to argue (attorneys notwithstanding), arguments can serve a useful purpose. They can clear the air, alleviate a misunderstanding, settle a difference of opinion, or perhaps allow us to agree to disagree.
For writers, our characters’ arguments can be especially useful. Sure, they can do all of the above, but they can serve other purposes as well.
