I would like to believe that the gambit Ursula Le Guin deploys in her review of The Year of the Flood works:

In her recent, brilliant essay collection, Moving Targets, she says that everything that happens in her novels is possible and may even have already happened, so they can’t be science fiction, which is “fiction in which things happen that are not possible today”. This arbitrarily restrictive definition seems designed to protect her novels from being relegated to a genre still shunned by hidebound readers, reviewers and prize-awarders. She doesn’t want the literary bigots to shove her into the literary ghetto.

Who can blame her? I feel obliged to respect her wish, although it forces me, too, into a false position. I could talk about her new book more freely, more truly, if I could talk about it as what it is, using the lively vocabulary of modern science-fiction criticism, giving it the praise it deserves as a work of unusual cautionary imagination and satirical invention. As it is, I must restrict myself to the vocabulary and expectations suitable to a realistic novel, even if forced by those limitations into a less favourable stance.

Since she ends up calling the book “extraordinary”, however, it seems that it doesn’t count for that much in the end. On the other hand, she calls the book “extraordinary”, which bodes well for me as a reader.
