In my latest Medium article, The Post-Race Future, I point out that the trend to write exclusively-minority casts and cultures, to make up for the lack of diversity in popular literature, is no more realistic than the monocultural literature it challenges:

When I come across a story that takes place in a modern or future world where everyone is of one racial group, or one cultural group, or one sexual group, I can’t help but think: How unrealistic. There are fewer and fewer places on this planet where you can go and see only one racial group, or one cultural group, or one sexual group… After eons of spreading apart, the world is now homogenizing; and that trend is more likely to continue than not.
