First of all, I think that's low. Second, how is that an argument for Catalan independence? Read our Declaration of Independence and tell me which of those grievances apply to Catalonia. Catalans are not oppressed. Maybe they pay more than their fair share of taxes but that's what national Parliaments are for, to resolve issues like that. You don't tear a country apart over this.
Look, I recognize that I'm in the minority on this issue here but I do not believe this will end well.
