Should English be the US's official language?

Do you think that part of the hostility in the United States concerning immigration-- particularly on our Southern border-- has more to do with xenophobia rather than "security"? Do you think that if we made English our official language, Americans would be less hostile toward immigrants?

I am particularly interested in the discussion surrounding the Spanish-language anthem. Please check out the mp3 audio of this anthem, linked from the following NY Times article: http://www.nytimes.com/2006/04/29/washington/29bush.html

Monday is the official day designated for immigrants to walk out of their jobs here in the U.S., as a form of protest. I'm worried many of these immigrants will loose their jobs-- what do you think?

Excited for a great discussion,
Bird
