Catalan independence movement declares a general strike in Barcelona

It is consultation that is prohibited in the constitution.
Not on a whim.
Because that question generates political problems when it is not binding and can be used to obtain economic returns.

Not only was there a referendum, illegal and that the international community claims was falsified, there were people who voted up to 4 times.

There were also thefts of money and private data of people. use of the Catalan police to generate disturbances, laws of disconnection from Spain were enacted, they were applied against the majority ignoring the legal procedures and forcing them, after part of the defendants have escaped while awaiting trial.

a whole set of crimes that have been ruled in a court that is sedition

Spain has never been against the re-entry of Scotland. (Neither left parties nor right parties)
Spain does not want quick entry without the process that all new states that want to enter must go through.
The position of Spain is the same since joining the EU
everything you tell me about what politicians say in the UK is new to me, I don’t say that newspapers lie, I say that politicians only say the part that interests them and people think that Spain has said something more than not has said. (strange behavior for a politician!)

I understand that there are states that can regain their independence, I understand that Vermont or New York do so and are in their right, I suppose it is something similar to the case of Scotland. (is sovereignty subject, a historical right)
Catalonia is not and never has been a state, it is an administrative unit, the state is Spain, it is a part of a country (an economically rich part) that wants to become independent.
Within Catalonia there are parts that want to leave and parts that do not, then they will give the option to become independent to the parties that do not?
The answer is no (they have already clarified it to the protests of these parts that do not want to become independent).

Horrors amplified with videos of Turkish police and selected by the same independence.

In Spain, when someone realizes that he is not right, he often uses the Nazis to try to win the debate.

Arguments: Spaniards = Nazis then a violent and independent minority can do what they want.
It is curious that the Catalans are not considered Nazis since it was the favorite province of Franco.

Spain is in the European Union, to enter the rest of the states studied its constitution and said it is democratic and the proof of them is that it is within the European community.
