I'm fervently opposed to Catalan/Scottish/Confederate/wherever independence because I do not believe that parts of countries with democratic governments should be able to easily leave whenever they happen to disagree with the rest of the country - but I am disgusted by the actions of the Spanish government today.
You should bring that exact question up with regards to Irish independence in the 1910s and see what some of our Irish posters have to say about being a subject minority nation in a country with democratic representation and how well that worked out.
