No, some arguments are constructive and informant. It also gives you an opportunity to discuss matters with people around there world and get to know some situations first hand. It can help you make friends with people you might never have the chance if not for a message board.

There are a lot of reasons I'm addicted to spend some of my time here. Statistics of my experiences shows arguing with you is not one of them. :p
