These jurisdictions want the rest of Canada to butt out but that's wishful thinking. Sure, the comments are at best counterproductive but hey, this still is a democracy where people have the right to speak and be heard. Politicians are only kidding themselves if they think that their remarks are going to be helpful. They won't.
It's sort of like the delusional conclusion that especially federal Liberals believe: that the wonderful Clarity Act is a country-saver when it isn't any such thing. If separatists win a referendum, the choice then becomes fight a civil war in that province or let her leave. Guess which option is the only realistic one in 2026. Exactly.
So, think about serious political reform in this country or be prepared to let Canada go.
Maybe it'll happen and maybe it won't but there are no political guarantees going forward. That's called reality. Keep that in mind.
