Mexico was most powerfully my father's smile and not, as you might otherwise imagine, not language, not pigment.

Bilingual-education advocates say it's important to teach a child in his or her family's language. I say you can't use family language in the classroom - the very nature of the classroom requires that you use language publicly.

In some ways I consider myself more Chinese, because I live in San Francisco, which is becoming a predominantly Asian city. I avoid falling into the black-and-white dialectic in which most of America still seems trapped. I have always recognized that, as an American, I am in relationship with other parts of the world; that I have to measure myself against the Pacific, against Asia. Having to think of myself in relationship to that horizon has liberated me from the black-and-white checkerboard.

It is very curious that the United States and Canada both assume that diversity means only race and ethnicity. They never assume it might mean more Nazis, or more Southern Baptists. That's diversity too, you know.

So, rather than becoming multicultural, rather than becoming a person of several languages, rather than becoming confident in your knowledge of the world, you become just the opposite. You end up in college having to apologize for the fact that you no longer speak your native language.

Mexico is sex and Canada is mind. There is much about Canada that I find admirable - the treatment of immigrants, for example, particularly those from Central America during the recent civil wars there. But there is confusion too: I know of Croatian Nazis who are subsidized by the Canadian government to maintain their racist culture. There is Canada, trying to sustain diversity without knowing exactly what it's doing.
