Insider/Outsider Debate

I believe that there should not be a specific regulation as to who is qualified to write diverse/multicultural literature. I think that it is important to have literature out there from both insiders and outsiders. Although outsiders may not have directly experienced the culture, race, religion, etc.; they can still do their job and research in depth about whatever it is they're writing about. Yes, I do believe that insider authors have one up on the outsider authors and that it's important to see multicultural literature from the person who has actually experienced it. However, I don't think that this means that outsiders can't do just as good of a job researching and observing a diverse group and collecting information to formulate a solid text. I think the only requirement diverse/multicultural literature should have is that the author should have proper and accurate information about that diverse group. It does not matter if that author experiences it first hand or collects information from insiders, as long as the literature reflects accurate information about that certain race, religion, gender, etc.
