Language is one of the unifying forces of the American experience, and with such a diverse country, English spoken by all generations back to 1776 has provided a source of unity, together with a common history, and common principles (Equal opportunity, liberty, democracy etc.) to build the American character and nationality - as German is indicative of German nationality, and French to French nationality - or Spanish for Mexican nationality (which is why they have that as their official language) - So to is English for American nationality. TO understand English is to understand the Declaration of Indpendence, the Bill of Rights, the Constitution etc. - as a leading Senator has stated recently those of us who do speak other langauges realize that something is always lost in translation.
that is actually complete and utter rubbish (again) for the simple fact that in "chinatown" English was spoken only as a Second language and patrons to the stores there still had to deal mostly with broken English.
most of the people in Little Italy also spoke mostly Italian back a hundred years, in fact, look at most movies from the 70's and 80's it was such a common practice that there are many examples, the one that comes to mind is the priest in the Rocky Movies.
Spanish is NOT only indicative of the Mexican nationality, it is spoken in a lof of other places in south America all the way to argentina, and In Spain they speak both Spanish AND Catalan and no "chaotic" situtations have presented themselves, Even in England, both welsh and English are spoken in Wales of course, and again, not Chaos to be found.
this is a made up issue, I can't go out to the states without hearing a BUNCH of languages, somehow Spanish is an Issue

.
LOL, I buy my Tennis supplies from a Korean Lady that has her store in the states and she can barely string a complete sentence together, her mother flat out can't speak english.
yet, I've haven't seen anyone denounce this.
and guess what! I don't care either! it affects me if I let it affect me.
