What did Maniac Magee do not acceptable?

In "Maniac Magee" by Jerry Spinelli, Maniac Magee challenges societal norms and racism by crossing the divide between the East End and West End of his town, which are segregated based on race. While his actions of running into the West End and befriending people like Amanda Beale and the McNabs are courageous, they also provoke tension and conflict, especially among those who resist integration. His defiance of prejudiced attitudes and his refusal to conform to the town's divisions are seen as unacceptable by some residents.
