If the child is exposed to both cultures, they will grow up to be self confident around black people or white people.They will be proud of who they are. I have seen white girls have biracial children and raised them exposed to whites only. That is when the child develops insecurities about themselves. They don't like their hair, they don't want to interact with black people, because they think it is better to be all white, I have seen this first hand.My grandsons are biracial and they are proud of who they are because they have been taught that they come from a strong , proud, intelligent, black back ground! Therefore when they do encounter racism they stand tall and realize that this person is just ignorant!
