Sounds like a shitty amusement park. But no. It's a map of the Bible Belt:
The map is a depressing image for Americans and Canadians alike, because they lose Florida, and we lose our country. It's a real drag all around, unless they want to join the Dominion of Canada, and I can't see that happening any time soon. The last time they tried to annex us, it ended badly for St. Catharines, and then for the White House, and it's only gonna get worse. But they outnumber us about 10:1, so if the US did decide to move in, there's really very little we could do about it. Fortunately, there's plenty of room.
Don't get me wrong; there is much to admire in the States, and I welcome any poor Yankee who has had enough and wants to move to a more civilized society. And to be fair, the map as drawn gives us the best parts (or at least the most cosmopolitan parts), and while I know we be reluctant to give it up (or parts of it), there's a good chance Alberta would swing red. Quebec might take the opportunity to skive off, but they'll not get a better deal anywhere else, and maybe they'll realize that.
We have a lot in common, and have only had one major dispute (and it was before we even got our nationhood), but the fact remains that when I saw that image, I felt a little chill.
I am, to cliché things up a bit, proud to be Canadian, and amalgamation would be uncomfortable.
Incidentally, the website is about some sane and sensible things happening in the Bible belt, and it's reassuring. They're not all wingnuts, apparently. Check it out.
