My opinion is that unsportsmanlike behavior should be dealt with decisively. That is, if two players who enjoy arguing end up in a match, their game should be handled differently – the judge doesn't interfere at all, only records the result. So, if one player reports a victory, and the other confirms it. If no one confirms, then both lose – so they learn good manners.
I think you're confusing the judge with the host. Where else should the judge intervene if not in situations where both players can't agree? – this can happen to anyone, why generalize or make sweeping statements.
