The SciFi channel did an adaptation of Le Guin's "Earthsea" fantasies recently. Many people were very angry about the series' portrayal of nearly all the main characters as white. Ursula Le Guin herself hated the series for many reasons, but above all this "whitewashing." She is strongly influenced by Taoism and Native American spirituality, had mostly brown and black characters, and felt with justification that a white Earthsea could not do justice to her work. She wrote that she's had letters from teens of color saying they couldn't find people like themselves in any YA science fiction but hers.
I've put up a community to protest this bowdlerization, save_earthsea. Everyone's invited to take a look at it and join in suggested projects for protest and in discussion about the racial issues involved, including to develop new projects friendly to people of color.
Thanks for reading this!
