For starters (regarding the bolded) one can take into account that there is no majority in Catalonia for Catalan independence. That should not serve to dismiss the number of independentistas as a small minority but the difference (percentage-wise) to those not wanting independence is considerably larger than, to quote a current example, that between UK Leavers and Remainers.
For soup, the rioting of the extent and nature we currently see is not representative of the vast majority of independentistas, on the contrary, most condemn it as being totally detrimental to their cause.
For the main course, Spain is governed from Madrid on the national basis (regional parliaments of lesser authority notwithstanding) and not from Barcelona. A little but nevertheless significant item that the Catalans not only agreed to when the constitution was put to the national vote, but actually helped writing into that same constitution.
For dessert (finally) those Catalans clamoring for independence and, more idiotically, constantly pre-occupied with an inflated sense of identity, are in convenient denial of their real origin. Which stems from the fact that the Romans, upon their retreat from the Iberian peninsula, left the footsore and the venereal behind at the Spanish side of the Pyrenees, so as to traverse the mountains more easily and thus get home faster.:mrgreen:
