Re: Curious Spanish attitude
While I don't agree with Rajoy's actions , what you are missing is that in terms of the Spanish constitution, ALL Spaniards should have a democratic say in whether or not Catalunya should be independent. It also seems to be what a fair few Spaniards think. Some of those I have spoken to are Ibicencan catalan speakers who think Catalunya should abide by the rules of the constitution they are currently part of.
Personally, I think both Spain and Catalunya would suffer economically if they separate. I also expect Madrid is concerned about the route to the rest of Europe being controlled by Catalunya.
