UPDATE: For Standing With Beck, Media Matters Claims Palin Supports Terrorism

Former Alaska Gov. Sarah Palin rebuffed Media Matters' requests to repudiate "erratic" TV and radio host Glenn Beck with a call into his radio program Thursday morning, saying, "I stand with you, Glenn."

[F]rom my kitchen table in Wasilla here’s the deal. You are up against one of the richest…and most powerful men in the world…the extreme left wing king, with many, many minions! So when I speak of your love of our Founding Fathers, and how you’re helping to educate Americans about respecting our nation’s history so we don’t lose what makes America exceptional. And the far left wing mouth pieces their twisting and spinning and perverting that message. I go back to what Abraham Lincoln said about standing anybody with who stand with anybody that stands right…I stand with you, Glenn.

Palin went on to deride Media Matters' "pathetic" and "desperate" attempts to silence Beck.

By Thursday afternoon, Media Matters was condemning Palin's remarks, go so far as to claim she supports violence and acts of domestic terrorism.  Media Matters' founder and CEO David Brock released the following statement:

On Tuesday, I asked Sarah Palin to use her influential voice to stop attempted incidents of domestic terrorism incited by right-wing extremists like Glenn Beck. By telling Beck, 'I stand with you,' Palin -- Fox News' star contributor -- now associates herself with acts of violence and the insane conspiracy theories and hate speech behind them.

Rather than seize the opportunity to act in the national interest and do her part to prevent a major tragedy like the Oklahoma City bombing, Palin called into Beck's show to call me 'pathetic.' While Palin and I don't agree on much, I honestly believed we shared the view that the incitement to violence by a powerful media outlet was a national crisis that transcends the partisan divide. Sadly, I was wrong.

The progressive People for the American Way is also working with Media Matters in a boycott of Beck's programming and the Fox News Channel.  The group's president, Michael Keegan, joined Media Matters in denouncing Palin, comparing her friendship with Beck to President Obama's past ties to leftist radical Bill Ayers:

For someone who was so quick to smear Obama for 'palling around with terrorists,' Sarah Palin doesn't seem to take threats of violence too seriously when they're generated by her own pals and allies. Even the last few days have seen disturbing thuggery in states around the country.  This shouldn't be a partisan issue.  Democrats, Republicans, independents and even tea party members should be able to agree that inciting listeners to violence isn't acceptable.  It's profoundly disappointing that someone laying the groundwork to run for president doesn't agree with that.
