Viewed through this lens, these governor's schools' purpose becomes obvious: they are ideological camps for the elite liberals to propagandize children. The purpose of the schools is to remove the children from outside support systems and then essentially brainwash them with the whole hideous circus of political correctness. They learn to doubt everything that they've been taught about their culture, religion, and nation. And into that doubt is placed a combination of radical relativism and socialist dogma.
Notice also the recurring theme from the kids that they now feel "elite" after what they've learned....and that their old friends and family are "simple" and "superficial". One of the ways which the liberals have propagated their philosophy (esp at the Ivy League universities) is to pose their ideology as much more "sophisticated" than the surrounding country. This has a natural appeal to young people....who like to feel that they are "hip" and "on the cutting edge". Now that they've adpoted this worldview, they rise above all others around and are members of the blessed annointed (Hillary has been caught in this stage of lefty development for several decades).
Frankly, the whole description of these schools reminds me of my freshman orientation at Brown. The liberals have this gig down to a science.
I wasn't aware of this angle. I can see how this would be very seductive for high schoolers. I remember how insecure I was at that age and how important positive reinforcement from faculty was to me. It's frightening to remember how utterly naiive I was. There but for the grace of God go I.
