you've said that it happens around you, which doesn't even touch what's happening in the rest of Britain

Between 1990 and 2010 I was in a job that took me all around the country and I was lucky enough to be able to book my own accommodation. One of the main criteria for booking a particular hotel was its proximity to a folk club and a lot of the time I was successful. I was not away every week and I did have repeat visits but I estimate that I visited folk clubs all over the country at least once a month for 20 years. That is approximately 240 visits. Many of the visits were to the same folk clubs (Bracknell, Leeds and Newcastle spring to mind as receiving multiple visits) but over the course of that 20 years I can count on one hand the number of times I was disappointed.

Terms like "purist" and "finger-in-ear"

Terms that I have never used in earnest. Take that up with someone else.

You have not address my findings and the findings of others who said they waked away from a scene became as rare as Dodos and the standards abysmal

Yes I have. See above. I fully accept that standards have slipped in some instances but can assure you that it is a rare occurrence rather than the norm. It is mentioned more because it is rare. Things going well do not make the news. Things going badly do.
