I think here in the UK things changed a bit with Brexit.

In the days of Thatcher I think most folkies were firmly in the left camp and knew exactly where they stood, although there were one or two right leaning supporters who probably kept quiet because they liked the music.

With Brexit you were faced with a choice of supporting either David Cameron and Tony Blair or Rupert Murdoch and Michael Gove - total arseholes on both sides of the fence. Most folkies did seem to support remain but I think there were probably more quiet Brexter/sceptics than in the pre-Brexit days.
