I don't think anyone needs to go looking for abuse it's pretty obvious when it occurs. The first warning sign to me is when I see a coach/parent verbally abusing a ref over a bad call. I've been around this sport long enough to have seen thousands of bad calls at every level. To date I have never seen one that was either on purpose or worth losing my temper over. That's not to say I won't try to correct a scoring error or such or attempt to get a rule interpretation from the head ref but I will not question an officials judgement. I will make my case right up to the point where ONE of us begins to lose our temper then the debate is over. When I hear a coach at the kids level say "I'm only sticking up for my wrestler", my antenna goes up. More times than not, that is not the type of person I would want coaching my child. They may be the best technician in the world but if they can't teach my child about sportsmanship, I don't want to be around them. I find it so sad to week after week see red faced coaches up in the face of a referee hollering about a judgement call. Then we wonder or make excuses for the kids when they get to a higher level and display the same traits when losing. Like I am prone to say "some people just don't have the temperment for this sport"!
