1. Spain will never give Catalonia a legal referendum on independence. They have stated time and again they will not let it happen, period.
2. Catalonians will never be able to change Spanish national law wrt this, because pretty much all non-Catalonian Spanish want to keep Catalonia, and are opposed to independence.
In practice, it's like saying that the Scots should have campaigned to get a legal referendum, in a hypothetical UK where the UK govt had flat out said "not happening", and the majority of the English/Welsh population were opposed to Scottish independence.
The Scots took over a century to get their vote and they have been a country for centuries which joined a union. Despite this they didn't try to hold an independence vote decades ago,without getting the support of the central government and they are a country.
They waited that long for their chance to vote,and guess what despite all the talk,people decided to stay. So was the independence movement as strong as many thought?? I dunno.
People seem to conflate that all catalonians want independence when even half their parliament decided to abstain,and more importantly previous informal votes have shown pro-unity tending to be more favoured.
This has been all engineered on purpose - the courts said no,the pro-independence lot did it anyway,and the local police ignored the courts,and then when the national police tried to enforce it,they obstructed them and crap happens.Why?? It was all engineered so they could gain sympathy from the world for their cause. This is classic tactics which have been used for 100s of years.
Also, remember when we go and support other movements abroad via military action,when people get shown emotive images on social media and "we need to act". Then we are shocked when the country goes to **** as apparently not everyone hated the old government.Remember,just because one side shouts the most,don't ever think they are the only side in any of these situations. Libya is a good example of a situation where we ignored the fact the people we supported would never be accepted by parts of the country.
Nobody is asking what do the Catalonians who don't support independence say?? No because they are not cool,and it complicates the narrative.Apparently nowadays the louder a group shouts the greater the legitimacy it has.
Moreover,Catalonia,AFAIK,has not been a proper country since the 1500s,so this is almost like London deciding they are holding a non verifiable referendum to leave the country since they hate Brexit,and the government says you must be joking,and then they do it anyway. No country would support that,not even this country. The excuse of "its taking too long" means nothing,otherwise it would mean anyone could make that excuse and make up rules when they want.
Why do you think so many governments are not backing this?? I mean I will just laugh if Sturgeon gets bored at waiting another 10 years for another referendum,and the nationalists in Scotland,decided to make up their own referendum and clear off anyway.
I am sure many here would be totally OK,with such a non-verifiable vote.
Anyway,since Spain is not Blighty I will leave it at that - we probably have more important things to sort out TBH!
