Every novel deals with social problems. It can't help it because the protagonist must come in conflict with his group. So the author has to offer an analysis of how the group and the protagonist fit. Otherwise, the reader will just say, "This makes no sense," and will put it away.

To really believe that others even existed in either category was to break the First Commandment.
