Two of the main social issues "To Kill a Mockingbird" are racism and coming of age. The issue of racism is primarily dealt with during events leading to, during, and following the trial of Tom Robinson. During those events, Atticus Finch must defend Tom against charges that are obviously not true. In the process, he must teach the town a lesson on equal treatment of people. During that time, Scout also must grow up in an environment of racial hostility and learn how to "walk in someone else's shoes. Her dealings with Boo Radley and Atticus' example teach her not to judge others on the basis of race, rumor or class.
