There is no "American" language
America is famous for being a melting pot of cultures from all over the world. While unity is a great goal, meshing several different ethnic groups and backgrounds together comes with challenges. The main hurdle is the language barrier that inadvertently comes along with mixing numerous ethnicities.
In America, the English-Only Movement has seen the near-extinction of Cajun French, Hawaiian, and Native American languages for the sake of “unity.”
In 1907, President Theodore Roosevelt wrote, “We have room for but one language in this country, and that is the English language, for we intend to see that the crucible turns our people out as Americans, of American nationality, and not as dwellers in a polyglot boarding house.”
Though we are a long way from 1907, some people can’t stand to hear anything other than “American.”
