You state: "denying political pluralism". I am of a limited intelligence so I had to research the multiple definitions of the word pluralism. I tried to use it in your argument and other arguments related to Scotland, Brittany, etc, but I can't get the same use of the word. The Catalonian referendum is pure pluralism "a form of society in which the members of minority groups maintain their independent cultural traditions." You clearly have other motivations, so as we are making things up I contend that you just want the land and money as you are not interested in having a multitude of cultures on the Iberian peninsula. You perhaps prefer just one so that it is efficient in making everybody the same and extracting wealth for the ruling elite.
