I absolutely agree, from what I read on the web, that CAMRA have hobbified cask ale, but that seems to be enough to allow small and medium-sized breweries to survive independently, which is basically the point of the exercise.
Furthermore, people are at least aware of real ale, even if they think it's for beardy saddos. Compare that to the Irish situation where so many drinkers have beer-blinkers on all the time, especially in the pub.
Honestly, I don't think we do talk pretentiously when dealing with beer drinkers of limited horizons. My attitude is usually: here try this before you order your usual, and if you don't like it that's fine. I failed in my late-1990s campaign to get all my friends to drink in the Porterhouse regularly, so I know there's just no convincing some (most) people.
Who's job should it be to promote quality beer? Us with our wallets, first. The small brewers with their distribution and marketing, second. and with luck the big brewers, scared into proper diversity, third.
I really don't understand why anyone would prefer good beer but drink crap, unless they're very poor or in desperate need of getting hammered. Have you discussed this over beers with them, Wobbler?
