Since you seem to not understand what is going on here, let me explain. She used the story of a white family who came in to receive help from her office to explain how she had to overcome her own prejudices. Further, in the telling of the story, she tells how they came in with something of an attitude(trying to act superior to her, despite needing her help). She further explains that she did overcome this, and did help them to her full extent, and did save their farm. All this is confirmed by the family in question.
Sometimes it is appropriate to make sure your side of a story gets out, and to ensure your partisan views get understood. However, sometimes it's time to admit you where misinformed, that you condemned some one who did nothing wrong, ad much right. Let's look at this woman you are condemning as racist: Her father was killed by whites, and those who killed him where never prosecuted. She had reason to be bitter whites. She turned this into a desire to help black people, and got the education, and got the job to do so. Then she was confronted with a white family. She started to do the minimum, but realized she herself was wrong in doing that, and turned her desire to help her people(blacks) into a desire to help her people(poor people). She overcame the racism that all of us have to some extent. She then went into a NAACP meeting, and explained to them that they too needed to overcome their racism. This requires a rather large amount of personal courage.
And you have the nerve to bitch about this woman as a racist...
