I think there's no fault in that.
Sometimes, people take things WAY out of proportions, away from the topic at hand no less, and it just spirals out of control.
And I think it helps people to sorta step back, maybe breathe a bit, and try again without all that arguing. Sides, forums in general are supposed to be places where you can relax, chat with people, maybe share a few ideas. All that arguing ruins the fun for everyone.
