MGM, not all folk club organisers are of the left, some are non political, some are centre, some do not want any political discussion at all. I have been around doing gigs for 49 years.
I have seen a lot of changes, most organisers are decent people who organise for a lot of different reasons, most of them do not want someone who is going to be cranky.
I remember one organiser complaining to me about a fat womman who complained about the bed she was offered, and another organiser who complained about the singer[still alive] who puked up and turned the mattress over, organisers dont want that shit.
