OK icanhandthemback my definition of a disagreement is an exchange of views or opinions that reveals that you don't agree about an issue. Such exchanges can be interesting and enlightening even though you may never agree. But nobody is hurt or upset.
But if that exchange becomes heated, confrontational, provocative, petty or aggressive, it is then an argument which could result in distress for either or both parties, and still no agreement!
I don't have a dictionary to hand to check the definitions so that's just my view - others may disagree!!
