Fighting IS very simple John, everyone can do it.
Now, fighting WELL, that is a different story my friend, as we know.
I've realized that those that downplay the significance of fighting in MA tend to be the ones that have never fought anyone of decent caliber.
I recall the first time I fought someone that shut down everything I threw at him, it was a lesson in MARTIAL arts that I have never forgotten and did more for me as a MA then pretty much any other single event.
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
