I agree this is not the best place for a political discussion of any kind, this is a site for chess. But the issue at hand is not just a mere opinion or something that you either like or dislike. Nationalisms should not be an option in place like this, where the issue at hand is not really understood. Why? an obvious reason, nationalisms encourage divisions and ultimately, if the leaders have the means, riots, disorder, waste of time and resources...apart from creating hates that have no reason of being among peoples of the same country. I think partisans of these movements do not really know what they are doing, nor thinking by themselves but instead allowing to be dragged by an idea with no foundation.I disagree with any kind of separatists but the most noisy ones are always Catalonia and the Basques...
Apart, I dont see any sense discussing something which has no relevance for anyone here...but at least, let it be known that the flag of ones country is not irrelevant!
Do the options of Galicia or Canary Islands also bother you?
