Great link.  Best part:

I am sick of recriminations and demands for retractions and counter-retractions and shocked outrage and line-drawing and line-crossing and apologies and non-apologies and boycotts and petitions. I am tired of watching every national debate inevitably pirouette out of the realm of morality, or merit, and into a rhetorical funhouse where insults bounce from mirror to distorted mirror. It's our dominant mode of political debate now: We don't evaluate arguments for their logic or elegance or force (or lack thereof), but for their appropriateness relative to metrics of racism, sexism, patriotism, religious bigotry etc.

I disagree with the premise.  It's important to stand up and speak out over this type of vitriolic blather that Rush utilizes as well as all actions of this type.  

This has hurt him, but more important it has empowered the consumer and all who have concerns that the voice of the people cannot be heard and acknowledged.

Axelrod is doing talking points to reporters using Limbaugh against Romney:

Obama political guru David Axelrod laid into Romney for his somewhat tepid response after Limbaugh said a Georgetown University student who wanted her college health plan to pay for birth control was a "slut" and a "prostitute."

"If you don't have the strength to stand up to the most strident voices in your party, how are you going to stand up to (president Mahmoud) Ahmadinejad?" Axelrod asked on a conference call with reporters.

from AFP, Obama camp mocks Romney over radio host, Iran, March 7.

Seema Mehta at the LATimes gives some of the other talking points from that conference call,  like "He's continuing to grind out a kind of tactical victory in a … death march."
