Our Loud, Proud Left - NYTimes.com
Douthat been's considering the argument over the resurgence of political correctness in the Left, particularly the academic Left.
I'm a touch on the skeptic side of this. While it does appear that there is a resurgence of silliness, particularly in American universities, I'm not sure that it is having much of a practical effect on society overall. In any case, Douthat's thoughts on it are not a bad read.
