My true view on it is, that I think Catalonia should stay part of Spain, but it depends more on which parties come in power in Spain, the previous government of Spain tried to stop the Catalan language as a main language at schools for instance, instead of crushing Catalan language, it has lead to this referendum. At that time I was certainly more pro independence than I am now for the moment.
The new socialist government is way more open to the Catalan culture, so at this moment I guess most people here don't really want the hassle of going independent at this moment, but that can change with every election to come.
So it depends more in what other Spaniards vote for.
Anyway, I still remember the imagers of the Spanish Guardia Civil kicking old people, that was really a shit stain on Spain internationally.
