I have no objection whatever to discussing the political implications of songs - that wa what my first song example was about, but I believe "Union activism has left tonnes of crops to rot in the field on purpose" heads the discussion off into an entirely new direction, (leading to a cul-de-sac as some of us have often discovered) - unless of course you can produce songs about workers having done so
I have no power to prevent this discussion heading in whatever direction the posters choose but I'd hate it to end up in a left-right catfight
