Agreed, with one proviso ...
Sometimes -- SOMETIMES -- the coach/trainer/administrator actually IS doing a lousy job. As a parent, should I just shut my mouth and keep forking over checks, or should I advocate for change?
When my child's coach/trainer regularly misses major scheduled travel events (with no explanation) and empowers an incompetent to take his place, should I NOT complain?
Defending or attacking ANYTHING blindly is a foolish position that can not be sustained over time.
