Our systems are our personal creation in a way few other things are and we , as they say in psychology, are "ego involved" with them. That said, it takes a real jerk to tell you that you have the wrong cables. Of course, it happens all the time on Audiogon. Audio is just another religion where many are not happy quietly worshiping in their own church but take it upon themselves to go out and convert the heathen to the true path. That being , of course, whatever they are using themselves at the time.
