Nor Chaucer The Wife of Bath's Tale, nor Shakespeare King Lear, nor Swift Gulliver's Travels, etc., etc. This is indeed nonsense -- it is a perceived slight where no slight is intended. As I recall, it surfaced some 15 years ago with the Virago Press and a novel about an Inuit woman by a non-Inuit author. The tumult that arose at that time from highly-principled but poorly-informed editors gradually died down. It was an attack on nothing less than the human imagination. People can imagine and write about what they want -- just try to stop them! But of course they had better do it well, or the voice-appropriation police will be after them.
