Seems to me a similar separatist argument could be made about various states here in the USA too. Texas is sure as hell different from the rest of us
In fact, some folks tried that once but Lincoln wouldn't hear of it.
Having travelled through the country, yes Quebec is definitely different from the rest of Canada, but IMO that's a good thing. Quebec should be proud of its differences while still being proud to be Canadian. It adds a decidedly not-boring aspect to the country.
By the same token, while Texas is definitely different - - practically another planet really
- - it'd be pretty boring if the whole USA were like Iowa
