Now, I can see how he thinks that color, race, and gender are being overly-emphasized in our current school sytem and I can also agree that that's not what makes up your identity and humanity, but calling it narcissm is way over the line, and that's not true anyways because if you're interested in your culture, then you're not preoccupied with yourself, but of other people in your culture. Oh, and by the way, RELIGION ISN'T A PHYSICAL TRAIT. It's an interest, and therefore should fall in his "criteria" of allowed extracurricular activities. People can change their religion, just like they can change their interests, activities, disposition.
Overall, Prager is trying to make a monotone school. He thinks that schools are providing too much extra help just because of physical traits, when it's the individual that really counts. Things like academic achievement should probably be left solely up to academics, but it's a bit extreme to completely swipe the school of anything pertaining to culture. In my mind's eye, I see Prager as an quixotic individual who is ultimately a hypocrite because his rules and regulations do not follow his "want" for individualism.
Lastly, trying to avoid political issues is ignorant, because some of those issues are legitimate problems that need to be addressed at a public high school. If you think about the amount of time students spend at school (more than a quarter of the whole day), and the often-seen disconnect of students and their families, sometimes the public school is the only place where education for these issues is possible.
And that's what I think.
