All I'm saying is that if you would speak to an instructor or master. They would tell you that they are involved in any martial art for more than the reason of self defense.
It depends on the instructor and the martial art. Some remain focused on self-defense through out their entire lives. IMO, that's a good thing, as these instructors are generally at the forefront in instructing law enforcement, military, rape prevention classes and other similar applications that to my way of thinking are beneficial.
