I had all this anxiety about what it meant to be a minority. My professors - the same men who taught me the intricacies of language - just shied away from the issue. They didn't want to talk about it, other than to suggest I could be a "role model" to other Hispanics - when I went back to my barrio, I suppose.

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.

Most American Hispanics don't belong to one race, either. I keep telling kids that, when filling out forms, they should put "yes" to everything - yes, I am Chinese; yes, I am African; yes, I am white; yes, I am a Pacific Islander; yes, yes, yes - just to befuddle the bureaucrats who think we live separately from one another.

When the Irish nun said to me, "Speak your name loud and clear so that all the boys and girls can hear you," she was asking me to use language publicly, with strangers. That's the appropriate instruction for a teacher to give. If she were to say to me, "We are going to speak now in Spanish, just like you do at home. You can whisper anything you want to me, and I am going to call you by a nickname, just like your mother does," that would be inappropriate. Intimacy is not what classrooms are about.

Learning can cause social fracture. Your people start expressing themselves.

The drama of the essay is the way the public life intersects with my personal and private life. It's in that intersection that I find the energy of the essay.

It's no surprise that at the same time that American universities have engaged in a serious commitment to diversity, they have been thought-prisons. We are not talking about diversity in any real way. We are talking about brown, black, white versions of the same political ideology.
