It is very interesting to consider a story like this. Just as, once upon a time, women writers were a minority — sometimes publishing under a male pseudonym to gain acceptance, and female characters in novels reflected stereotypical gender roles, it is often the case that ethnic minorities are not reflected in popular culture, including as characters in novels or as the writers themselves. The move to alter this imbalance is a positive one.
There has been a similar movement in Australia to include books and stories which reflect the experience of Australia's indigenous population and I worked on a project which encouraged Aboriginal students to write about their own experiences.
Diversity in modern and popular literature is an extremely positive move and I hope one which will be successful.
