In her full transcript she actually proves Breitbart’s case, when she accuses Repubs of being racists for opposing health care.
So, while allegedly proving that she no longer sees the world through racial lenses, she actually proves the reverse. She is not capable of seeing the world any other way.
In the initial excerpt aired by Breitbart, the reaction of the NAACP proves his case, his intent in airing the video in the first place. It had nothing to do with her, but for the fact that what she was saying demonstrated the inherent racism in that crowd. She cannot show Breitbart defaming her, damaging her, nothing to do with her. Her tort, if she had one, is with Vilsack.
