The fastest way to end an argument based in emotion is to counter it with one based in thought.
It seems as though the art of argument has devolved into a technique simply used by people to vent pent up emotion
. The beauty of an argument is that it strips away the boundaries of courtesy so that Truth may come out however ugly it may be.
But an argument without parameters is akin to boxing without a referee, where nothing and everything is a strike below the belt.
