Problem here is that your concept of censorship is a one way street. Just because the Franco regime was a brutal dictatorship does not mean that ‘progressive’ ideas automatically squash all alternatives. You mischaracterise the current political situation which is that a minority left wing government is trying to impose an amnesty it had ruled out during the electoral campaign - this has been very unpopular even with erstwhile supporters. Censorship is effectively being imposed - see the ousting of the El Pais editor - an unfortunate characteristic of Spanish governance going back long before Franco. For me, the key problem is the lack of tolerance of opposition on all sides - as a Spanish friend put it to me power means surrounding yourself with (political) friends and family (‘los tuyos) and screaming at those who oppose you. It usually doesn’t end well (see 1936) but success stories (the restoration of constitutional democracy in the early 80s) are possible. One final point - the book reading cultural elite is a tiny fraction of the population and does not have the right to automatically impose its ideas on the wider population - in Spain as elsewhere.
