This document summarizes themes of racism presented in the novel "To Kill a Mockingbird". It discusses how racism is shown through the segregation of white and black churches and schools. An example of hatred towards whites is shown when Calpurnia tries to bring Jem and Scout to her black church. It also discusses how racism influenced the unjust conviction of Tom Robinson, a black man, for a crime he did not commit. The document argues racism can influence people to act in uncontrolled ways and pass racist beliefs onto future generations, but Atticus opposes this tradition of racism.
