I think this is a PR problem more than a racist one. I don't know her, but you can tell she's a sweet, good-intentional individual with just a VERY uncensored and unfiltered sense of humor. She has to be taught to selectively watch what she's saying when shes out of the house.
I say this because she is exactly like someone I know.
And she sounds just like one of those Southern rednecks when she says "I have a black friend, and he's as black as this board. Come here, Hollis. They can't see you in front of that board." + the pictures that's surfacing with her + seven other white people + one dark-skinned black person.
