¿De dónde vienes amigo?

I've always thought it was poor taste to wear, in Zihua or in any foreign country, clothing that identifies my national origin. But it sounds like I should dig out my old Canadian flag t-shirt. Or maybe get one printed that says:

NO SOY GRINGO

I like seeing someone wearing something that identifies them as being Mexican, or Greek, or from any of a variety of countries that have not invaded my country, stolen our land, threatened to annex it, etc. In fact, I wear a t-shirt proclaiming “Hecho en Mexico” when I am not in Mexico, even though I wasn’t. (I’m planning to return that shirt to Mexico and give it to someone who really was “hecho en Mexico”.)

I can understand why it might be in poor taste to wave a French flag in Haiti, a Union Jack in a place that was subject to British imperialism, or an American flag in… well, a number of places, including Mexico. I’m not sure why it might be in poor taste for an Australian, or New Zealander, or Canadian to wear something discrete that indicates where they are from.

I like the "Hecho en Mexico" t-shirts, with the big eagle insignia. But the only one I could find in Zihua said:
"Hecho en Mexico, Pero Bien Hecho"
which I thought was a tad embarrassing.
