Is the cult of victimhood devouring itself?

David Brooks makes some good points about the ridiculous feud now developing between Clinton and Obama in this NY Times article. Here's a taste:

The problem is that both the feminist movement Clinton rides and the civil rights rhetoric Obama uses were constructed at a time when the enemy was the reactionary white male establishment. Today, they are not facing the white male establishment. They are facing each other.

All the rhetorical devices that have been a staple of identity politics are now being exploited by the Clinton and Obama campaigns against each other. They are competing to play the victim. They are both accusing each other of insensitivity. They are both deliberately misinterpreting each other’s comments in order to somehow imply that the other is morally retrograde.

Can't we all just get along?
