It is all a bit shit. But, you still can't ignore the fact that the majority of people are against independence. From your link...
'The Catalan government says 90 percent of voters in the referendum backed a breakaway, but turnout was only 43 percent as most opponents of independence in the region boycotted the vote, already declared illegal by Spain's Constitutional Court.'
Surely the Spanish government is obliged to act on behalf of the majority? I am in no way agreeing with their methods and actions.
