Political Correctness Run Amok

I heard that Rahm Emmanuel unleashed expletives at liberal senators last fall saying they were "f***ing retards" for threatening to run ads against fellow Dems who were holding up their vision of a government take over of health care. So what, this is news? He was right, get over it. If conservatives are going to argue that political correctness has run amok, which I assert repeatedly in this space, then we should just let this go. Is there hypocrisy on the left with regards to PC? Sure, but is that news either?
