It's hard not to be irritated by Matthew Parris. I remember once reading an article he wrote criticising Britain's railways (an easy target for lazy writers, of course) and praising Mrs Thatcher's 'great car culture' ideas to the high heavens. I found this intensely annoying due to its one-sided, patronising and arrogant tone.
Now he's tried applying the same tactics to folk music. I heard the Pick Of The Week comments and the same sneering tone came across clearly. Parris has a horrible knack of putting forward his opinions as if they are acknowledged facts.
I hope the BBC were inundated with complaints.

I've just re-read this thread before posting (always wise, of course). The Snail's assertion that Parris is 'well-known for being an opinionated pillock' is spot on.
