It is unacceptable to be of a different race and expect justice in the community. This is scene in the case of Tom Robinson, who is an innocent man convicted of a crime against a white woman. It is acceptable to let a white woman free from contempt of court because she is ignorant. It is unacceptable to be poor and rude. The poverty is held against the children in the story, as seen with Walter Cunningham. It is acceptable to harass and malign a young man who has been isolated for a long period of time.
It is acceptable to be a racist with little empathy for those who are different as long as you are a church-going white person.
