We write a lot about how liberal college kids are desperately searching for something to be outraged about. Without that constant sense of self-righteous superiority, they'd be no better than your average "student" and would be forced to learn something that actually matters.
They argue that, no, they're just concerned kids who see a lot of evil in the world and confront it whenever they can. They focus on current events and carp about whatever happens as if it was happening to them personally - all in an effort to change the world for the better.
