does Ritterhouse see a way for blacks and whites to overcome the racial etiquette?

In Growing Up Jim Crow, Jennifer Ritterhouse examines the social construction of race among the youth in the segregated South.  In five to eight pages discuss the concept of “racial etiquette.”  What was it and how did it manifest at the different stages (ie, childhood, adolescence) in the life of black and white southerners?  Why does Ritterhouse believe the etiquette effected whites more profoundly than blacks?  Do you think it has something to do with how blacks and whites relate to the ceremonial versus substantive rules of the Jim Crow culture?  Finally, does Ritterhouse see a way for blacks and whites to overcome the racial etiquette?
