Mexicans who come to America today end up opposing assimilation. They say they are "holding on to their culture." To them, I say, "If you really wanted to hold on to your culture, you would be in favor of assimilation. You would be fearless about swallowing English and about becoming Americanized. You would be much more positive about the future, and much less afraid. That's what it means to be Mexican.

If you want to live in Tennessee, God bless you, I wish for you a long life and starry evenings. But that is not where I want to live my life. I want to live my life in Carthage, in Athens. I want to live my life in Rome. I want to live my life in the center of the world. I want to live my life in Los Angeles.

My decision was sparked by affirmative action. There was a point in my life when affirmative action would have meant something to me - when my family was working-class, and we were struggling.

For me, diversity is not a value. Diversity is what you find in Northern Ireland. Diversity is Beirut. Diversity is brother killing brother. Where diversity is shared - where I share with you my difference - that can be valuable. But the simple fact that we are unlike each other is a terrifying notion. I have often found myself in foreign settings where I became suddenly aware that I was not like the people around me. That, to me, is not a pleasant discovery.

Those people who say that America is finite are some sense right. The environmental movement, for example, has a great wisdom to it: we need to protect, to preserve, to shelter as much as we need to develop. But I think this always has to be juxtaposed against the optimism of old, which is now represented in part by immigrants. I would like to see America achieve a kind of balance between optimism and tragedy, between possibility and skepticism.

Of course, San Diego chooses not to regard the two cities as one. Talk about alter ego: Tijuana was created by the lust of San Diego. Everything that was illegal in San Diego was permitted in Tijuana. When boxing was illegal in San Diego, there were boxing matches in Tijuana; when gambling was illegal, there was always Tijuana.

In some countries, of course, Spanish is the language spoken in public. But for many American children whose families speak Spanish at home, it becomes a private language. They use it to keep the English-speaking world at bay.
