There's a storm brewing over a book which was featured in a US sci-fi magazine, which has been criticised since the book revolves around the idea of a ruling race of dark-skinned people and an under-class of fair-skinned people, and HILARIOUS RESULTS that ensue. It sounds pretty awful and heavy handed, but from looking at it it doesn't seem that far off Malorie Blackman's Noughts and Crosses, which was hailed as a wildly brilliant study of racism.
Shouldn't sci-fi be free to explore these ideas? Or do too many writers in the genre abuse it to spread their nefarious ideas (thinking about how Starship Troopers was written/read as a white power text). Should that matter if the art itself is any good? I'm just kicking round ideas.
Kirk didn't mind what colour his alien ladies were, did he? Phwoar etc etc.
