Overwhelmed by the Spanish Language in the U.S.

I resent having the Spanish language pushed down my throat. It is on billboards, television commercials, political forms, product packaging on grocery shelves, business promotional materials, ads on the side of buses, in fast food restaurants, bank windows, and government offices such as the DMV and courthouses, and much, much more. English may not be the "official" national language of the United States, but it is and always has been the language that is spoken by the majority of the people who live here. All of a sudden, everything is written in English and Spanish. I resent having to bear the extra cost for this marketing, repackaging and rebranding. A countrys language is an important element in bringing about political and cultural unity among it's citizens. Historically, the American government has operated in English, I think it is time that English is officially declared our National Language. At the end of the day, I believe that a shared language would create a common bond among all the people of the United States of America.
