Form of government is all important to you. Substance thereof? Not so much, apparently.
Not necessarily. There are some democracies and republics that I would never live in, such as the People's Republic of California, or most European democracies.
But I would never under any circumstances live in a place where the head of state was a monarch who held real power and acquired that power by birthright. If said person attempted to rule the United States, I would join the long line of people waiting to put a bullet in his head.
