Years ago, a regular at a local folk club, Kevin Littlewood ( he of On Morecombe Bay ) wrote a song about the woman of Greenham Common and a number of folk club supporters didn't like thrust of the song and were talking about boycotting the club.
I've never heard of anybody reacting like that to a Dylan protest song.
Maybe, Ewan was right for criticising Dulan for being too general with his protest songs.
