More propaganda from the secessionists. You have been using institutional resources to spread your ideas for forty years, it is more than clear to everybody that your freedom of expression is not in jeopardy.
Tell that to the two catalan rappers accused of "hatred" on behalf of their (tame, by rap standards) lyrics that taunt spanish policemen. One is about to enter prison and the other one is on exile in Belgium.
You could argue that "hatred" is in jeopardy though, if you feel it's worth.
