I'm always a bit on the fence on this. I mean, logically, she's right. As a writer you get it in the neck either way – either by writing about characters from cultures that aren't yours (appropriation) or lack of diversity (and navel-gazing) if you don't.
I don't think it's less prevalent in the world of fiction than fashion/music, either. Just look into the storm around this book –
the Orenda – and there have been loads of others.
The problem (or one problem) with saying that people should only write from within their own direct experience is that lots of people then wouldn't be represented in fiction at all – e.g. historical novels, or most childrens' books. OK, so we've all been children, but no adult has been a child living now so any writer for children using a contemporary setting is making a big imaginative leap. Similarly, most writers are educated and almost by definition literate – so it's hard to write from direct experience about people who aren't. But should those people not be represented in fiction?
An example – I love Roddy Doyle's
Barrytown novels, set on a deprived Dublin estate. My favourite is The Snapper – which is the story of how Sharon, the unmarried daughter of the family, gets pregnant/has a baby, a lot of it from her point of view. Roddy Doyle is surely doing a pretty brave thing there because as a middle class male some would argue it's not his story to tell on numerous counts...but it's a fantastic book, and how many other popular novels give a voice to a young, uneducated, unemployed girl who finds herself pregnant and at odds with her community? And makes the reader feel completely sympathetic, completely inside her head?
Having said all that...
I do think there is something about authenticity. You can smell it and recognise it, and I don't think just being an excellent writer who uses their imagination gives it to you. Take Roddy Doyle again. He was a teacher for years in communities like Barrytown, so even though he wasn't of that community, he had lots of opportunity to observe and listen. Would he have got that authentic feel just by using his imagination?
Or take The Wire – the best TV drama series I've seen, about drugs in Baltimore. The people who created it had worked in journalism, the police force and the schools system there for years (and some of the actors were “off the street”) and I just don't think a team of writers who had been to film school and then spent their working lives as writers in Hollywood would have been able to create it. (In fact maybe this is one of the reason that so much film and TV these days comes from books – because then they know there is already an authentic “core” to the project – they are not relying on screenwriters to somehow create that?)
So I do think writers have to be bold and ambitious and all of that, and think it's pretty astonishing that this writing festival disowned her for saying so...but there is another side to the argument.
