I do not consider you are in a position to judge folk clubs if your judgement is based on watching an occasional you tube clip.
The point of a club is that it is inclusive, the idea of NTMC that residents sat on a sill behind the performers in an elevated position, this type set up often creates a them and us situation,it gives an impression that the residents on the SILL were better or more important than visiting singers.
To criticise a particular aspect of a folk club has nothing to do with being a dictator.
HVING A POLICY THAT INSISTS ON EITHER TRADTIONAL ONLY, BLUES ONLY, OR SONGWRITERS ONLY IS PURIST, the fact it is purist does not automatically mean it is bad.
I am afraid in my eyes you are reminscent oif Don Quixote because until you tell us how often you have visited uk folk clubs when you are living in ireland you are in a similar postion to Don Quxitoe in that you are off on imaginary or NON EXISTENT VISITS
