No, everyone harping on Breitbart missed the point. He wasn't trying to attack Sherrod. The point of his video was to show the reaction of the NAACP audience.
Listen to the video when she was explaining how she initially felt about the farmer in question. The audience is almost shouting their assent. They are AGREEING with her.
When she finally got to her "moment of truth" when she realized that she was was engaging in her own brand of racism, the audience went silent.
THAT is what the tape was about.
So, maybe Obama fired her because he realized she wasn’t a flaming racist anymore?
Sadly, far too insightful for far too many.
