As said before, this 70% of the local population would represent, lets say, a mere 10% of the total population.
So if one of each ten people voted for "yes to A", and the other nine people voted for "no to A". What should happen in a democratic system?.
Well, the idea here is that you has the freedom to choose among two nice options: "yes to A" and "repeat the process until yes to A is achieved" or "start negociations to circumnavigate what people really wanted". But this is not a dictatorship, of course; we are a democratic modern society unlike the spaniards, those savages.
And talking about semi-naked savages, this reminds me that extra-nice 2008 campaign launched by Catalonian independentists: "support a spanish child with more money from Catalonia". It seems that this is how they see the other spaniards. Nice image. It isn't?.

Because poor children is a perfectly fine theme to make some good laughs (They are poor, ha-haa!).
To finish, and taking in mind several harassments and repeated BS like this in the last decade, I think that a lot of people in Spain would vote enthusiastically about sending this people out of Spain, even better, why not to Mars?, to build the New Castelldefells and live their futuristic utopia happy forever in the red planet.
