It's not a matter of "safety," since the time I went to Tijuana,
Mexico, and I didn't have the Maple Leaf on my car, my car got broken into and my backpack stolen because in
Mexico we are assumed to be "Americans" and that's what the world does to Americans!!! It's not "dorky" to not want to become a victim to something that was really meant to happen to an "American." It's not stupid, it could save your life! And even here in "Mother England" I have to wear a Maple Leaf big enough to land
Air Canada with, just to keep from getting assaulted or beaten up walking down the streets of London, although because I'm female on top of that (and also First Nations, "Red Indian" to these people) there are some other issues working there; a female First Nations Canadian may not be safe anywhere in the world outside of Canada (and I hope I'm not saying "outside of the reserve," because I'd hate to think that I'm heading back to some sort of hibernation away from anti-"American" attacks!)
Not that it works; people see the Maple Leaf and start treating me like "American" anyway. It helps to analyse how much of "you're an American!" you can tolerate being told to you, not asked but TOLD. And how much of being treated like the world sees them you want to have to live down... as we Canadians all know, the world views "Americans" in a certain light, from imperial terrorists imposing their wishes on the rest of the world to just plain stupid, ignorant fools, among other things. America is all in the media, all in the news, and all over the world. So how many Maple Leaves you want to wear and where, depends on how much "you're an American!" you want to hear. I've been away for 8 months and I'm ready to stop looking for more Maple Leaves to put on clothes and bags and things and my forehead and about to call it quits and go back to the Reserve.
And as for getting robbed, that would happen anyway. You might get robbed for being Canadian, (I did, even here in so-called "safe" Mother England) but without it would be even worse, because then, again, "you're an American!" and you might personally get attacked as well as robbed. The world thinks that Canadians are all rich, that our streets are paved with gold, but without that distinction, guess what, the world thinks that about "America" too. So there's no getting away from that probability.
