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.

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.

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.

Cultures, when they meet, influence one another, whether people like it or not. But Americans don't have any way of describing this secret that has been going on for more than two hundred years. The intermarriage of the Indian and the African in America, for example, has been constant and thorough. Colin Powell tells us in his autobiography that he is Scotch, Irish, African, Indian, and British, but all we hear is that he is African.

What really terrifies Americans is the prospect that the Indian is very much alive, that the Indian is having nine babies in Guatemala, and that those nine babies are headed this way. This is one reason why Americans hold on so dearly to the myth of the dead Indian.

But lots of emerging racial tensions in California have nothing to do with whites: Filipinos and Samoans are fighting it out in San Francisco high schools. Merced is becoming majority Mexican and Cambodian. They may be fighting in gangs right now, but I bet they are also learning each other's language.

Affirmative action ignores our society's real minorities - members of the disadvantaged classes, no matter what their race. We have this ludicrous bureaucratic sense that certain racial groups, regardless of class, are minorities. So what happens is those "minorities" at the very top of the ladder get chosen for everything.
