I think what immediately rubs me the wrong way with this is that Anderson right away hits on a couple of pet peeves of mine.
First, he mentions that children's fitness pursuits should be leading to sports teams (or they arent really valid, at least, that was the implication I was left with, though I tend to be really sensitive on this issue). I used to coach high school volleyball, and when I saw what parents would force their kids into for a 'scholarship' when the kid didn't have the heart or real talent to play in ANY college, let alone Division 3, it was upsetting, for everyone involved. Not everybody needs to be forced into that mindset. Team sports are not the only way to be fit and active, have discipline, work hard, and succeed.
Second, that at 15 years old, a child will have mastered the basics of pole dancing and all advancement past that occurs only in a strip club. I think both sentiments are incredibly closeminded. In all other forms of dance (ballet, modern, ballroom, hip hop, etc, etc, etc), in yoga, in gymnastics, in circus arts, in capoeira, in martial arts, there is no ceiling to what can be achieved; no dead ends in the art itself. I could go on and on.
