As a Canadian I would be horrified if they banned all speech related to separatism. Quebec should absolutely be entitled to rant about wanting to separate themselves from the rest of Canada. That's not extremist speech, there is no realistic risk of violence from that speech, it's just a widely held (slightly less so recently) political opinion about how we should organize ourselves into political bodies.

I don't know what issues Spain has with separatism, maybe there are some legitimate ones, but not all separatist groups are inherently bad.
