I'm not much of a one for off-the-peg ideas, but Phil at "Oh Good Ale" completely nails this debate to the wall. I don't necessarily agree with everything he says, but he nicely sums up the intricacies and pitfalls of the question.
My point of view is that trying to find a category name for the beers that we enjoy isn't as important as explaining why they taste like they do. Once people understand what malt, hops and yeast are (I'll take water as read), and how they contribute to flavour, then things might start to change. It's easy to preach to the converted, but a bit harder to talk to the merely curious.
Having spent a decade doing that (talking to the beer curious) behind the counter of what was once a fairly good off licence, but is now a really great beer shop, I can tell you that explaining people what makes a beer great isn't as much fun as drinking it. But as always, education makes a difference, education is the key.
POSTSCRIPT: I'd also point out that education cuts both ways. I've had plenty of people ask what makes American beers taste the way they do, and on finding out that it is largely American hops, they've asked which beers don't contain American hops. And that's just fine too.
