State government buildings Spanish signage

Is government buildings signage in English and Spanish only discriminatory and state sanctioned Hispanic favoritism? Where are all other languages?
Why not just us the international symbols system for foreign visitors rather then the state sanctioned discriminatory method currently in place in Utah?

In the United States, English is the national language only in an informal sense, by numbers and by historical and contemporary association. The US Constitution does not explicitly declare any official language, although the constitution is written in English, as is all federal legislation.
On May 8, 2007, Senator James M. Inhofe (R-Okla.) introduced Senate Bill S.1335, which would declare English as the official language of the government of the United States. The bill would require that the U.S. government conduct its official activities in English, repeal federal bilingual voting requirements, and
require naturalization ceremonies to be conducted solely in the English language. The bill contains a provision preventing it from pre-empting any law of any U.S. state.[10]
Previous incarnations of this bill were co-written and supported by Ron Unz, a California millionaire. He, along with his organization (U.S. English), has been pushing for the "English-Only" cause for many years.As of May 2007, several bills relating to English as a national language are pending in the U.S.House of Representatives.[11][12][13]
