Scholars have characterized To Kill a Mockingbird as both a Southern Gothic and coming-of-age or Bildungsroman novel. The grotesque and near-supernatural qualities of Boo Radley and his house, and the element of racial injustice involving Tom Robinson contribute to the aura of the Gothic in the novel. Lee used the term "Gothic" to describe the architecture of Maycomb's courthouse and in regard to Dill's exaggeratedly morbid performances as Boo Radley. Outsiders are also an important element of Southern Gothic texts and Scout and Jem's questions about the hierarchy in the town cause scholars to compare the novel to Catcher in the Rye and Adventures of Huckleberry Finn. Despite challenging the town's systems, Scout reveres Atticus as an authority above all others, because he believes that following one's conscience is the highest priority, even when the result is social ostracism. However, scholars debate about the Southern Gothic classification, noting that Boo Radley is in fact human, protective, and benevolent. Furthermore, in addressing themes such as alcoholism, incest, rape, and racial violence, Lee wrote about her small town realistically rather than melodramatically. She portrays the problems of individual characters as universal underlying issues in every society.
