Gee,if we were to ban everything with the the socially unacceptable version of Negro, we'd be able to get rid of Rap music.
This is BS, pure and simple. This was an actual portrayal of how people thought and talked in less enlightened times. To ignore the usage of the word and mask the way the people were treated is like denying the holocaust.
Confronting and discussing these attitudes is the only way we can move beyond them. Pretending it didn't happen or hiding the reality of the situation is a disservice to those who fought to be treated as equals. They endured ignorance and persecution, and their stories need to be told.
This knob gobbler likely didn't get All in the Family either, while they were sipping their non fat soy milk and grazing on organic granola.
