describe how momma is a "realist"

Momma is a realist regarding race relations. She speaks her mind and stands up for herself when she deems it necessary. She, however, is a realist when it comes to conflict with white people. Momma knows the cost of confrontation far outweighs any benefit. Even when nasty white kids make fun of her, Momma keeps her composure. In other parts of her life, Momma is a realist as well. She loves her children but tries to prepare them for the harshness of the world.
