The point is: even if everyone on the fierceboard discussed this and came to the conclusion that it is not appropriate, there is exactly nothing that would change. Things would only change if parents would stop letting their kids cheer at Cali because they don't like the way Cali runs their gym. That's the way businesses work.
If you are looking for a higher standard: find yourself a gym that has them. But from personal experience I can tell you that it is a lot more important how you raise your kid. I doesn't matter what a coach or a teacher tells them. It matters what you tell them and what you exemplify to your kids through your life.
And if you don't like the way the producers edited the whole thing there is an easy thing to do: don't watch the show. It's the same thing as with the Cali-parents: if you don't like something don't give them money (and yes, everyone who watches the show gives them money because that's just the way youtube works).
There are tons of TV-shows I don't like because of the way people are shown there - the easy solution: I don't watch them!
