Fellow traveler Kate Shea Baird sums it all up quite well. I feel it's important for those of us on the left who support Catalan independence to remember that we want independence in order to deliver a better country. Not just any country. An independent Catalonia, sí o sí, is not the aim and never should be. I don't consider Catalans to be living under a repressive regime (unless you mean the Mossos) and so I don't buy the liberation trope. And while I wouldn't like to see Artur Mas behind bars for organizing the consulta, I'd crack the cava open if he and the rest of his party were sent down for corruption.
The pro-independence left (mainly the CUP and elements of Iniciativa and a handful of people at ERC) must maintain its focus through all the twists and turns in this process. We must, above all, fight for our values as the keystone of our support for independence: we want a better country. We want a country that helps the poorest, defends labor, looks after its citizens' health, educates its young people, invests in the arts and culture, promotes sustainable living and tourism, and rejects CiU's corruption and the neo-liberal model. And because we're on the left, we must want all these things for Spain as well.
That's the Catalan republic that I defend.
