Not allowing high school students to read realistic novels such as To Kill a Mockingbird is analagous to the parents who do not explain the "birds and the bees" to their teens so that they will not engage in any sexual activity. Will these children not, then, find information from some other source? Besides, with all the information in the media of news and movies, etc., are students nowadays not acquainted with offensive language and perversions of all kinds?
Interestingly, Harper Lee's novel is taught in the majority of high schools in the Bible Belt state of Alabama (where "bad language" is frowned upon), a state also renowned for racial conflict. Now, if this novel is state-approved there, what does censorship of it say for other states that consider themselves "liberal-minded"?
Part of the interest that is generated in the teen reader is its address of controversial issues. Clearly, teens want to know about life, and Lee's novel is a great tool for teachers to address with them issues of their concern.
