I am too old now, but I did face the dilemna in RL in the late seventies.
In 1976, the
Parti Québécois was elected in Quebec with a platform to declare independence from Canada.
For those who are old enough to remember, that election was as much of a schock in Canada as Trump's election in november.
During the early days, 1976-77, there was much wild talk on both sides, of the Canadian Army being sent in to declare martial law and of civil war. I did have several discussions with friends back then, most of which were ready to take up arms if that happened.
I too was ready to fight to defend my country, but was torn between my country being "Quebec" or "Canada".
Thankfully, this being Canada, passions soon cooled off and I never had to make a choice.
