When I published my post Some Questions for a Catalan Independentist, I hoped that people would engage with the questions and enter into spirited debate. I later realised that to deal with them properly, each question deserves its own thread. I hope that this helps to foster a polite and friendly debate on the topic. I should also add that these are my questions: I don't claim to have presented an infallible or complete list of concerns, and I'd be happy to receive suggestions for new ones from readers. I'll deactivate comments on the original post, so as to continue debate in these new ones.
The first question is the shortest: Why exactly should Catalonia be independent?
