Check out her quote from a 1999 documentary entitled ‘Homecoming’:

Shirley Sherrod, Albany Office, FSC: It makes you wonder sometimes why is it that it took Farmers Home Administration that long to, to send a notice. Why is it that the county supervisor didn’t send any kind of letter, you know, leading up to getting’ the delinquent notices in ‘87. So many strange things happen when you have only white people in charge of dealing with our people.

Ah. It was a 1999 documentary that she was quoted in. Perhaps it took five years to make and get it aired, so maybe we are approaching the 20+ years ago where she stopped being a racist.
