There is no Catalonia issue and you have plenty of freedom to express yourself wherever you want. We must remember that Catalonia has already held two legal referendums, where the result has been a refusal of the Catalan people to leave Spain or Independence. Apart from not having any historical reason for independence, it is very funny how you talk about a lack of freedom of expression in a country that has suffered 40 years of dictatorship and where people like my own grandfather were shot for expressing their ideas. Take a walk through Qatar, Chechnya, Hong Kong, China, North Korea ...etc and value your freedom to express yourself on the Internet, your grandparents surely died for it. Respect the dead, read a little about the history of Spain and do not make the mistakes of generalizing.
