Fair enough. But you know, we have encountered hostility, either declared or covert, from virtually all of Europe's footballing establishment. As we have, and still do, from England's footballing establishment. What that tells us is less about Barcelona FC specifically, than about how the ruling class — however you choose to take that term — firmly intends to remain the ruling class, and intensely resents anyone breaking into that very closed circle. In football as in many (all?) other domains.
Beyond their specific relation to us, in the bigger picture, Catalonia, of which the city of Barcelona is the capital, represented serious resistance to the Falangists who ruled Spain with an iron fist for so many years. That is a mitigating circumstance for me.
