Do you think genre writers wouldn't accept the term from outsiders? I was half-joking my comment to sartorias above, which crossed with yours - but maybe I shouldn't have been? Quite possibly I don't hang around with professional fiction writers enough to pick up on these things.

I really like Attebery's distinction - though it's pellucidity at the level of theory doesn't mean it's always easy to place any particular text (hence his use of fuzzy sets). But the people making this argument aren't the ones at Readercon!
