People who behave in a combative and dogmatic manner have not programmed in to themselves a check to ask "does this issue really matter?". There is no decision making code in their brain to work out if something REALLY matters. Many things, even small things, matter enough to go to war. They also value the war/being right/the point more highly than they value maintenance of positive human relationship. What they don't understand is that people forget the issue and remember the grace (or not) with which you handled it. Often they are not very good at empathizing with others and find it hard to imagine what it is like to be someone else interacting with them. I know cause I am one, hopefully reformed.
