Maybe you're the one who needs to learn a new language: Respect.

This is very offensive. My first language isn't English, and my parents don't speak English well either. Yet we have the same right as anyone to be here. This country is first and foremost about freedom. It's important to take into account the cultural diversity in our country. It's a good thing, and seeing it as an annoyance just seems bigoted and prejudiced.

America is a country of immigrants. "Our language" is not English. It's Spanish and Chinese and French and German and Japanese and every language in between. What you're basically saying is that Spanish and Chinese are not as valid as English.

"learn our language or go home"? America is our home.

"... by allowing a language barrier to exist inside our country, they are potentially limiting the progression of the country."

While I agree that a language barrier can impede progress, there's one hitch in your position. Why should everyone learn English? Or rather, why just English? How many people do you know who were born in English-speaking households that can speak a second language? I've been to a school in France where they start learning a second language at the age of ten, and I stayed with an Austrian family for five days and spent time with a fourteen and a fifteen year old who spoke English as well as I do, and better than half the people you see on the internet. Why does the solution have to be that everyone else must conform to our standards? America is supposed to be the Melting Pot. We blend together bits of every culture in our music and our art, and English itself is made up of bits and pieces from other languages (Which, by the way, is what makes it hard to learn.) Why can't we try to meet the rest of the world halfway, instead of cutting ourselves off by insisting that everyone speak English? 

I must add one more point as well - from your article, it sounds like the only reason you brought up the issue is because customer service recordings and telephone operators have options for other languages. The thought that it inhibits progress seems to come second to that. Just so you know, if two is Spanish, one is probably English. Just press the button.
