Here's an anecdotal analysis from a longtime Californian.
It's a longer piece but it reads well. One bit I'll excerpt (but it's worth reading all)
Fresno's California State University campus is embroiled in controversy over the student body president's announcing that he is an illegal alien, with all the requisite protests in favor of the DREAM Act. I won't comment on the legislation per se, but again only note the anomaly. I taught at CSUF for 21 years. I think it fair to say that the predominant theme of the Chicano and Latin American Studies program's sizable curriculum was a fuzzy American culpability. By that I mean that students in those classes heard of the sins of America more often than its attractions. In my home town, Mexican flag decals on car windows are far more common than their American counterparts.
I note this because hundreds of students here illegally are now terrified of being deported to Mexico. I can understand that, given the chaos in Mexico and their own long residency in the United States. But here is what still confuses me: If one were to consider the classes that deal with Mexico at the university, or the visible displays of national chauvinism, then one might conclude that Mexico is a far more attractive and moral place than the United States.
So there is a surreal nature to these protests: something like, "Please do not send me back to the culture I nostalgically praise; please let me stay in the culture that I ignore or deprecate." I think the DREAM Act protestors might have been far more successful in winning public opinion had they stopped blaming the U.S. for suggesting that they might have to leave at some point, and instead explained why, in fact, they want to stay. What it is about America that makes a youth of 21 go on a hunger strike or demonstrate to be allowed to remain in this country rather than return to the place of his birth?
