It's hard to argue with To Kill a Mockingbird 's message of standing up for what's right even when the costs are high. But not everyone agrees that the book holds the moral high ground. While the main reason it frequently appears on lists of banned books is its use of profanity, it's also been challenged for its one-dimensional representation of African-Americans as docile, simple folk who need whites to protect them. Some people see the novel as taking a powerful stand against racism. Others just see it as promoting a kinder, gentler form of racism.
