Why is the left acknowledging political correctness now?

It started recently with a Jonathan Chait article.  Reading a post where a liberal is at least suggesting that political correctness might not be such productive thing was as improbable as seeing a unicorn run across the sky on a rainbow.  PC has been their stick since I first saw it rear its ugly head.  Yet there he was, trying to differentiate the ‘left’ from politically correct culture, as if there is any difference.

We get another variation on this theme here, and even Kevin Costner is openly saying the race card is a means to silence dissent.  Leftists trying to distance themselves from political correctness?  To those of us who believe that the most cynical answer in politics is usually the most correct, this can’t possibly have anything to do with an epiphany on their part.

It’s possible the ‘Hands Up, Don’t Shoot’ crowd was the moment they realized the monster they helped to create and found so helpful at one time is seeing them as just more kibble along with us brutish conservatives.  Truly rabid PC is something that won’t stay inside polite boundaries or go back in its box, and now it’s biting them too.  It wouldn’t do for them to stop being special and have the PC enforcers shrieking at them.

Either that, or they see it finally imploding and this is their attempt to distance themselves from their own disaster.  It wouldn’t be the first time leftists have blamed failed policy on someone else when it finally irritated enough of the normal people.  If the payment for the piper is coming due after all the decades of dancing they’ve done?  It’s not going to be fun for them.
