Uncle and Nephews
On the one hand, we see a law-abiding uncle, Ruslan Tsarnaev, who's willing to condemn terrorist bombs even from relatives and, on the other hand, we see his nephews, Tamerlan and Dzhokar Tsarnaev, who apparently sent off the terrorist bombs. Maybe we should see that they had in common and how they differed.
What they had in common: Uncle: Muslim immigrant from the Caucasus; nephews: Muslim immigrants from the Caucasus. How they differed: Uncle: did not attend American schools; nephews: attended American schools. Maybe the schools were the problem.
I suspect that anti-American ideology in public school is more dangerous than anywhere else because, at least as far as youngsters are concerned, school is the Voice of the Establishment. If the Establishment says the Establishment is wrong…
Addendum: On the other hand, sometimes schools teach courses I approve.
