Greg Lukianoff on The Coddling of the American Mind

Worth a look.
I'm not wild about his and Haidt's approach. The most important response to PC victimology involves stating the reasons why it's false and unreasonable. Arguing that it's psychologically harmful, or the fault of the Boomers, or whatever might be effective--perhaps even more effective. But it's beside the point. The point is that PC is wrong. The other point is that the PCs need to grow up, buck up, and recognize that if you're wrong, you're wrong, and no matter how hurt your feelings might be, it doesn't make you right.
