Sometimes arguing a point also to the potential for negotiation. It gets you to what the other side really wants. Lots of times they don’t really want what they’re arguing for, or something else would be just as good. Sometimes one of both of you come to the conclusion that what you were arguing about wasn’t the best of best ideas after all. You weren’t seeing the whole picture.
But you have to go through that process to get there.
We’ve erroneously gotten to the point where we think that everything is a conflict of morality and that conflict is bad and must be avoided.
Shame on us.
