Close your eyes, hold your breath and hope the situation resolves itself, that's your solution? I don't believe in a: "hidden human need/instinct to argue with people". There is nothing hidden about human conflict. It is as natural as any conflict; as natural as space and time. In fact, without conflict evolution can not exist. Obviously, a good portion of the arguments being had have the potential of bearing no fruit, but I would argue that just as many of them not only should but NEED to be had, and are quite productive on the whole.
