One of my coworkers says to me: "I can't help it I'm slightly racist"

<<<don't get me going>>>>
She CAN help it, it's a choice of attitude to be racist, it's not in one's DNA. To alter that choice may require a deep examination of where the attitude came from ( family of origin, bad experiences, stereotypes) and then making an attitude adjustment. Most people don't want to work that hard.
