This is why borders are important, because borders are a mechanism for like-minded people to live together and be ruled by their own consent (the consent of the governed). If the USA is to remain a Constitutional Republic, people who live here had better mostly believe in the Constitution.

What better borders than property lines? If the people around my neighborhood have some right to impose their "collective will" upon me simply because of proximity, then surely the people of the US have the same right to do so to the people of Canada, or Mexico; they're "in our neighborhood." And why stop there?
