Answer:
Racism is the most important and most abundant topic in To Kill A Mockingbird. The town in which To Kill A Mockingbird is set in is called Maycomb County, where everyone gossips and where everyone hates African Americans. Throughout the story, Atticus accepts a case in which a black man was accused of raping a white woman. Clearly, the black man was innocent, but he was still convicted guilty. This just shows how much prejudice is in this book.
