Well said James – you are right about what is needed to live alongside the true Spaniards in Spain. What Spain doesn’t need, I suspect, is more vast areas devoted to loads of ex-pats who go to Spain to try to create another patch of “little Britain”. I experienced this scenario when living in Cyprus.
Nothing isolates individuals more than not even trying to learn the language of the country you are living in and not attempting to respect their culture and traditions. That happens all too frequently in UK!
