This is Weaver's Hierarchy of Discussion. It's a good tool to check yourself against when you're arguing with someone. The closer to the top your method of address is, the more effective it becomes in actually convincing the other party.
I've seen a lot of name-calling on the boards and in the chat. While it is "immature," a person of any age can take a lesson in basic logic and learn that being louder or more rude does not make one more right.
Just something to think about.
