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.

You learn in America to speak two ways. You learn in public discourse not to be very specific about your religious life. Or, if we talk about it, we'll find a secular way of doing it that will not be offensive to people of non-belief. So, that you go through life with these alternate voices.

My grandmother would always tell me that I was hers, that I was Mexican. That was her role. It was not my teacher's role to tell me I was Mexican. It was my teacher's role to tell me I was an American.

I had an Indian face, but I never saw it as Indian, in part because in America the Indian was dead. The Indian had been killed in cowboy movies, or was playing bingo in Oklahoma. Also, in my middle-class Mexican family indio was a bad word, one my parents shy away from to this day. That's one of the reasons, of course, why I always insist, in my bratty way, on saying, Soy indio! - "I am an Indian!"

It is not simply that these two cities are perched side by side at the edge of the Pacific; it is that adolescence sits next to middle age, and they don't know how to relate to each other. In a way, these two cities exist in different centuries. San Diego is a post-industrial city talking about settling down, slowing down, building clean industry. Tijuana is a preindustrial city talking about changing, moving forward, growing. Yet they form a single metropolitan area.

I find L.A. very interesting, partly because I think something new is forming there, but not in a moment of good fellowship as you might think from all this "diversity" claptrap. It's not as if we'll all go down to the Civic Center in our ethnic costumes and dance around.

The fact that we're all hyphenating our names suggests that we are afraid of being assimilated. I was talking on the BBC recently, and this woman introduced me as being "in favor of assimilation." I said, "I'm not in favor of assimilation." I am no more in favor of assimilation than I am in favor of the Pacific Ocean. Assimilation is not something to oppose or favor - it just happens.
