There is a difference between an argument and having a knock down drag out fight. For example when parents have a disagreement about how to deal with catching their child sneaking in drunk after a party. This can go many ways but for the purpose of highlighting the difference take Chris and Pat. (argument) Chris: Pat, I can understand how you'd feel that way, but considering the family history of alcoholism, maybe we should take a more conservative approach with this. vs (flame war) Chris: Well, Pat... Maybe if your mother had cared half as much about you and your brother growing up as I'm trying to care about our kids and cracked down on you guys a little bit, maybe your brother would have stopped at that red light, and maybe your kids would have an Uncle.
