Diverse Lit.: Insiders or Outsiders?

I think that diverse literature should be reserved for  'insider' authors only. Not to stifle freedom of the press, but to accurately and respectfully represent an entire culture. I do not use the term 'entire' lightly, because if someone - child or not - reads just one book about a particular culture, that my be the only source they have for creating generalizations, which, as Cortes describes, can easily turn into harmful stereotypes. I think it is important for minority groups to voice their own experiences, rather than read an interpretation of a culture by a majority party. Bishop's article Selecting Literature for a Multicultural Curriculum addresses this issue quite nicely: "the father a writer's background, knowledge, and experiences are from the culture of the person or people about whom he or she is writing, the greater the necessity for the author to fill the cultural gaps, the greater the effort needed to do so, and the greater the risks of mistakes." (Bishop, 17) I think this quote brings out the true issue at hand: accuracy. Is it truly accurate to write about anyone else's life experience but your own? I have a hard time arguing that it would be, which is why, for my initial thoughts on this issue, I think 'insiders' should be writing diverse literature.
