For some reason, I'm somewhat sickened by the idea of an American studying up on Canadian politics just so they can come off as NOT American.
On the other hand, maybe the people who buy these will, in learning about another country, realize that there are indeed other countries in the world. Unfortunately, I doubt the people who most need to learn the lesson will.
But yeesh, if they don't want to be an American, they should move. (Although I doubt you guys up north want 'em either.

)
If they're so worried about people's response in other countries, they could always wear a Kerry t-shirt or something. (Anyone who hates America's current administration's policies but thinks he's president probably isn't worth talking to anyway.)
