Argument: English is not under threat nor needing protection
Linguistic Society of America Resolution on English Only. July 1, 1987: "The English language in America is not threatened. All evidence suggests that recent immigrants are overwhelmingly aware of the social and economic advantages of becoming proficient in English, and require no additional compulsion to learn the language."
Linguist Geoffrey Pullum, in an essay entitled "Here come the linguistic fascists," points out that English is far from under threat in the United States, and argues that "making English the official language of the United States of America is about as urgently called for as making hotdogs the official food at baseball games."
"Is the primacy of the English endangered?" MassEnglishPlus.org: "No, the primacy of English is not endangered. It's already the de facto language of the United States. English is the de facto language of the United States. All public business, and most private business, is conducted in English. Foreign businesses who do business successfully in the United States require that their salespeople learn English. What we should support instead is the mastery of a second language or multiple languages. For American business to be competitive in our global market place, knowledge of other languages and cultures is crucial."
"The Myth of English as a Threatened Language." MALDEF on OpposingViews.com: "Official English and English-only policies are founded upon the myth that the primacy of the English language is somehow under threat. In fact, more than 92 percent of our country’s population speaks English, according to the last Census. This confirms that the problem English-only laws are designed to address simply does not exist. Moreover, English-only laws are built upon, and help to perpetuate, a baseless stereotype that immigrants, particularly those from Latin America, do not want to learn English."
