Personally and to the more general topic, I am greatly in favor of involved PARENTS striving to get their children educated to the highest possible standards that the kids are capable of. If this person / book is a challenge to others, let them take that challenge.
Frankly, in today’s USA, the problem is in the detached parent(s) wanting the village to raise their child.
An equally disturbing problem are parents -- liberal and conservative alike -- who think their children are brilliant, uber-talented, super-special, etc., just because the child is their offspring and regardless of actual achievement.
The problem is they include the urban ghetto ‘culture’ in the mix of what they call American.
Remove that and our culture jumps dramatically up in the list.
