What factors play in to Wright's cultrural heritage

Wright taunts and mocks the Jews living in his community along with numerous other black children. Wright calls them “Christ killers” and sings cruel songs about them. Wright justifies his actions through his “cultural heritage”. By ‘cultural heritage’ Wright means the experiences and interactions he had with the people around him, especially the adults.
Wright has known racism his whole life. He notices his mother cooking for white people but he has no food. He hears the news of a ‘white’ man beating a ‘black’ boy. He realizes that it doesn’t matter the color of your skin; if you have any African-American relative, you are black. Wright is beginning to grapple with the knowledge of racism. He is trying to understand it and yet fit into his own culture at the same time. But Wright is realizing his culture is racist as well. As he grows up he learns that he and the white boys are filling their racial roles “as though they were being guided by instinct”. Wright doesn’t flat out say in his book that he knew his racist actions were wrong, but rather illustrates for the reader his lack of understanding at what he was doing.
