We can’t be surprised by the right-wing ignorance about Dr. Martin Luther King Jr. and the politics of the 1963 March on Washington. Today’s conservative leaders are the political descendants of the forces who fought the civil rights movement as a radical, most likely Communist plot. When the movement turned out to be wholesome and all-American, when a quarter of a million marchers descended on the capital without riots or violence 50 years ago, well, then, it had to be co-opted, it had to prove that America was living up to its highest principles, that those noble people were satisfied with what the system gave them — a Civil Rights bill and a Voting Rights bill — and they went home, and marched no more. Dr. King’s assassination five years later made it easier for them to do that.

There are so many ignorant right-wing reactions to this anniversary to talk about, but the award for the most vicious and stupid has to go to radio host Laura Ingraham, who insists that those of us who are commemorating the 50th anniversary of the march this week are trying “to co-opt the legacy of Martin Luther King into a modern-day liberal agenda.”

Actually, Ingraham is so wrong, she’s sort of right. Liberals did co-opt King’s radical, anti-corporate and antiwar agenda long ago. The King we commemorate today is a friendly shadow of his challenging, radical, visionary self. (Read Harold Meyerson on “The Socialists Who Made the March on Washington,” for a necessary corrective.)

But that’s not what the ignorant and vicious Ingraham was saying. She’s pretending King was some kind of conservative hero whose message of colorblindness – and that wasn’t his message at all – has been co-opted by liberal race-baiters and whiners and malcontents, who just won’t accept that Bobby Jindal is right when he talks about the “end of race,” because a first-generation Indian immigrant’s experience of racism is identical to that of people who were enslaved for hundreds of years, and he gets to decide when racism is over. Ingraham’s co-opting comment was just dumb. Typically dumb. What was unusually vicious, even for the often nasty radio host, was that she decided to interrupt an audio clip of the heroic Rep. John Lewis, the youngest person to speak at the march 50 years ago, speaking on Saturday, with the sound of a crackling gunshot.
