Random thoughts I may try to put together cohesively:
Respect is to be earned, not demanded. Geniune respect that is, not just a display per protocol. A person is not necessarily respectable by virtue of age or rank. Both elder and child abuses are abuses of power and intorelable in a society. And they happen.
K & C is public, very public. Teaching and learning take place everywhere but not in the same manner in public as in private. Public bashing by an authority is almost never productive except in cases where ability to take such bashing is considered part of the job or a show of being "man enough" to take and learn from it, more commonly expected in macho occupations such as in the military and in tough and rough team sports.
A skater and his/her coach are a team, working toward a common goal. Or they should.
If a coach is upset simply because of a poor performance, it's about his own ego. I think most coaches' upsets are frustrations at their skater's failure at certain aspects of skating the coach has tried hard to teach or thought have been overcome by the skater. It does not necessarily have anything to do with how much the skater has practiced. There is simply a failure of a lesson taught or learned or a premature expectation. The coach has shared responsibilities in such failures and the team needs to work it out. An initial silence, especially in public right after the performance, may just mean both the coach and the student are absorbing the situation, figuring how to deal with both the emotions and the remedy.
Obviously I'm against public berating, or private ones for that matter, of anybody, especially minors. It's an abuse of authority and unfair downloading of emotions and shared responsibilitie. Respect needs to go both way. The coach is supposed to be the mature and wise one so s/he should be examplary. S/he should consider different ways of teaching and motivating the student, including bringing in specialists who are more able to impart knowledge in certain areas. If the coach and student are not competible and the relationship is not conducive to the skater's growth, then the relationship should be terminated, as when either party is dissatisfied or even frustrated with the other. Otherwise it's not a healthy relationship which will only hamper the skater's progress or worse.
OTOH, to show some empathy for the coaches who may have lost it occasionally at the K&C, it's not necessary a normal pattern of their relationship. We only get a glimpse of their interations, like children who witness the parents' scary fights but not the private making up and other happy interations.
