@ConnorBrunniche We can work toward a movement/organisation that demands it while openly arguing that to achieve it would require a break with capitalism, at least at the European level, and that a bourgeois government cannot achieve it. That might sound impossible but I don't see another way.
@ConnorBrunniche Yes we can demand it, but that is different from trying to get a liberal party to adopt it as policy, as an aspiring government of the British state. Which as you admit, would likely lead to a coup and therefore surely demoralisation.
@ConnorBrunniche If you want a communist organisation and programme, why not think about what plausibly could bring this about, however difficult and unlikely it is.
@ConnorBrunniche If even a mild programme would face enormous pressure from the forces of capital (and probably collapse the government), I don't really see how pushing the Greens to become His Majesty's Government and try any of this stuff is that helpful? Sounds like a recipe for demoralisation
