Young Jenna is incensed (and properly so)at the concept of "white privilege." The problem, I think, isn't so much that her teachers take an ideological position but that, based upon her link to the excerpted material, they do it in such an insipid fashion. There may be something called white privilege but who would think so based upon the material that was apparently assigned to Jenna and her classmates. It paints with such a broad brush as to be incredible.
A lot of this stuff reminds me of the old SNL bit "white like Eddie." Eddie Murphy puts on "white face" and finds out that the world is a party and money is free.
All he really had to do was read some of the stuff that passes for social science "literature."
