Why be aggressive at all, either passive or argumentatively? People tend to react defensively to aggression anyway, which is counter-productive to achieving any sort of understanding. If you have a problem to resolve it's possible to simply discuss it like adults and work it out. If the person you have a problem with refuses to listen, there are no rules against kicking them and if they react aggressively, the ToS actually works against them.

Basically, you can do fine in life without having to argue or being rude.
