Democratic governance depends on the consent of the governed. When the governed don’t consent to be governed anymore, you can sometimes force them to shut up, but then you don’t have democratic governance anymore, you have tyranny.
Secession, handled democratically and in good faith, is an option. Secession carried out by violence is only justified when the seceding polity isn’t represented in the government. If your region has one vote and the other regions have 8 votes, and a vote goes against you, that’s not justification for secession. When the other regions execute your people without trial, then suddenly you have justification for violent resistance.
And how exactly do you think extrajudicial murder of pro-secession leaders is going to work? Like, you call up some soldiers and tell them to go over and kill a couple hundred people? How exactly do these soldiers expect to avoid murder charges? How exactly do the leaders who order the murders expect to avoid murder charges? Murder is a crime in just about every country, you know, and murdering your political opponents is frowned on in most civilized societies.
In fact, that’s the difference between living in a civilized country and an uncivilized country. In nekulturny Russia, you can just have annoying people killed without trial, and face no consequences. This is what makes Russia nekulturny. Is Spain supposed to be a liberal democracy with the rule of law? Or a fascist dictatorship? Spain tried the fascist dictatorship thing for quite a long time, ask some random Spaniards if they want to go back to Francoism.
If Mariano Rajoy can pick up the phone and get a bunch of soldiers to murder a couple hundred Catalonian separatist leaders, and get away with it, then he’s not the elected leader of a democratic country, he’s a fascist dictator. You think if he has to power to murder Catalonian separatists with impunity that he’s only going to use that power against separatists? I mean, if you can murder people and get away with it, murdering journalists who annoy you is a pretty good idea, as well as murdering people from opposing political parties, cops who try to investigate your crimes, people who don’t pay the bribe money, and on and on.
Is Spain going to be the type of country where annoying people are killed by government Death Squads? Or not? Because if it’s going to be a Death Squad type of country, that’s going to have some pretty far reaching consequences. Like being kicked out of Europe at the least. Where’s your pragmatism now?
