I am a UCD almnus (class of 2007) and classifying the student body as "mildly conservative" is not accurate. Nor is the claim that most students come from the central valley. Most students come from the San Francisco Bay area or other population centers around the state, and most students, like college students everywhere, are liberal-leaning.
I agree that most protests do not effect the changes they strive for, but I don't think the "right to protest" is something you should give away so casually. You pay the salaries of the people who assaulted your classmates and you don't seem to care. There is some form of protest on the quad virtually every week, and only recently have our campus police forces (across the US, not just Davis) started breaking them up.
