Spain criminalizes protests- including "insulting the state":

18. The Fascism - Communism fault line in Spain is very deep

It's like a grand canyon because it was related to the Spanish Civil War were the military under the direction of Franco and aided by Hitler and Mussoluni tried to overthrow the government and only the communists offered resistence. Because Franco was unable to capture the major cities, it was a very slow coup-d'etat with many atrocities and large scale purges mainly on the side of Franco.

That war was followed with years of dictatorship when the liberals were brutally repressed. Franco's handpicked successor got blown up by the ETA and he thought that the former king would make a good alternative, however the King instituted a democracy. Nevertheless the Conservative Party (PP) headed by Rajoy and under W. by Aznar is Franco's party. The old Franco clique was never held responsible and continued as the "People's Party."

That is also the reason why protests in Spain are on massive old-fashioned communists scales with often 100,000s of demonstrators. And it still Fascist vs Communist which has been renamed as Conservative vs Socialists.

I remember a Spanish girl a decade ago who proudly said that she was a communist and you should hear the screams from the Ameuro crowd who didn't know that in Spain the communists are still often considered the good guys.
