Conflict is a form of communication, and common sense simply doesn't exist; that is, there is not a way to see things shared by everybody.
But conflict is not violence, and a person one confronts is not an enemy. Debate is conflict. Suggestions are often conflicting, and result in compromises. And different ways of playing end up in countless conflicts through this forum.
There's nothing wrong with expressing passion, until it hurts someone. If one feels hurt, he should always let some time pass before responding, so the passion lowers, and feelings can be told in the content of the text, not in its form. 90% of the times I read someone being hurt, I don't actually see anything hurtful in the text; people take things personally, which is a form of egocentrism, whereas whoever wrote was also thinking of self (obviously). If ones gets hurt by a comment, one should read it again and again. The point is not to agree, but to accept what the interlocutor says before answering, because the words are feelings and thoughts, not tennis balls to be thrown back and forth until exhaustion. The form is what makes a comment pleasant to read, but the content is what does matter.
If you find a conflict to be sterile, just leave it. If a conflict makes you think, keep going. The way I see it (without knowing the details), the conflict you are referring to is needed: there is a big mess that noone wanted, and many want to know who is hurt, or to tell that they are hurt, and regrets need to be expressed, points of view given, until all remember that they are talking about a game. So let it flow. You'll have to discover where it leads; probably to the recovery of peace.
Ah, and to handle a conflict, it's always good to have a mediator whom everyone would accept as a neutral ground. Like the wise old women councils of our long lost matriarchies. I know, that's not so easy to find.
