LOL. Valid point. I will agree that there can in theory be a winner. However, how often do you witness acceptance and acknowledgement of defeat from the defeated party on the interwebs? That is where the endless defense and offense from each respective position continues to perpetuate a seemingly endless debate. I suppose that should be my revised statement.
How often? 100% of the time in the single case, at least, of the exchange between the two of us. I made a point which was gracefully acknowledged by yourself.
I concede of course, that there are personalities more inclined to be argumentative than others, and when two such find themselves at loggerheads, the party may last longer than many of us wish to stay.
Fortunately, the exit door is always open, and we are free to spend our time elsewhere, ...but those who hang-in-there for the spectacle may still notice a previously undiscovered gem or two flung along with the other substance.
I prefer that point/counterpoint be calmly engaged in (and accepted) as "discussion", rather than cringingly avoided as "argument".
I am pleased to have exchanged (peacefully) these few thoughts with you.
