The central idea of To Kill a Mockingbird is discrimination. Throughout the novel, many of the residents of Maycomb held prejudices against others based on their social status or race. For example, Mrs. Dubose judged Scout and her father negatively. Additionally, the townspeople spread exaggerated stories about the mysterious Radley family and feared Boo Radley without truly knowing him. Prejudice and ignorance also led to misunderstandings between black and white characters, such as assumptions about Mr. Dolphus Raymond. In the novel, discrimination takes many forms including prejudice, hatred, and ignorance.
