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.
The roots of cultural and political division between Catalonia and Spain go back centuries and can't be easily watered down to "leave whenever they happen to disagree with the rest of the country." Likewise for everywhere else you have mentioned.
