Just to play devil's advocate here: how consistent are you on sovereignty?
I myself am a world federalist, so am not particularly sovereigntist. Sure I believe in decentralization with power shared eqaully even with local, national and world governments, and so on that front do support moderate sovereignty, but certainly not absolute sovereignty. So I can say that I am consistent on the questions of both Canadian and Quebec sovereignty. It would just be a question of whether Quebec and Canada would each have their own national governments, or whether a united Canada would have one national government within this larger world federation, and so as a result, I'm quite indifferent to Quebec sovereignty since I see it more as just an administrative issue, kind of like determining provincial boundaries or municipal boundaries.
On the other hand, my question to those who are Canadian sovereigntists who oppose Quebec sovereignty, is: how do you reconsile two contradictory philosophies (i.e. federalist at the Quebec level but sovereigntist or "separatist" at the federal level by opposing NAU etc.)?
