Oh no. They already been told they must do what the separatists want. Thats how democracy works in Quebec.
There's no way that would hold water. Even if Quebec had any sympathy internationally, that political capital would be obliterated the moment PQ starts playing double standards.
Unless PQ could entice the FN to join a sovereign Quebec, but then they might actually have to treat the FN as equals. Good luck finding agreement there.
Not that Canada's treated them any better, but then again this might be a good thing as PQ and Canada work at enticing the FN to stay with them.
