self determination is the ultimate right of any people. The Catalans have every right to self-determination.
Madrid zealously supported Slovenian & Croatian independence in 1992 after illegal referendums. Why is this time different ?
Madrid lost all legitimacy when it unleashed paramilitaries upon peaceful people trying to vote. When one needs to bludgeon little old ladies for peacefully expressing a opinion; you no longer have any legitimacy to govern.
You do realize that the Catalans are communists, right?
Yep.
