The Disempowerment of Ethnic Studies?

Anyone who's followed Ashley Thorne's posts describing the recently discontinued La Raza/Chicano "studies" program in the Tucson public school sytem may well have experienced a sense of the surreal: how on earth did this balkanized, ideological bomb-throwing find its way into any classroom anywhere? Could anyone actually have been serious about a "curriculum" that could only engender ethnic chauvanism and antagonism toward non-hispanics, especially whites? Unfortunately, yes, since the Tucson program is simply an extension/imitation of what's been going on in academic precincts for quite some time now. Here you can easily find any number of undergraduate courses and "studies" programs devoted to fostering group identity, group chauvnism, group grievance, group entitlement, etc., etc. But as these two pieces (here and here) in the Chronicle of Higher Education illustrate, ethnic studies has apparently been catching some flak, even from within the academy, and the authors respectively write to mount a defense. Of course, they believe, lots of criticism predictably emanates from the incorrigible racism which perdures at all levels of American society, and which was recently made manifest in Arizona's new statute which effectively terminated the Tucson curriculum. But one of the authors interestingly argues that ethnic studies programs at the college level have been weakened by academic "liberals," who have used them as a means of celebrating "diversity' rather than generating political activism and group advocacy (as in "empowerment"). That, he concludes, is where ethnic studies needs to refocus, as the La Raza program was apparently doing so well. As the comments thread indicates, a number of academic observers with first-hand experience of similar programs also think that's exactly what's wrong with them.
