I've read some of the answers about latin people and spanish language in the usa and I wouldn't have imagined how some people there are so racist. The USA is an empire, like it or not, and you want everyone and everything to revolve around you. Why would you learn Spanish, French or German since in Spain, France or Germany you will speak English and natives will answer you in English. Of course, in the USA you must speak English and English is widely spoken everywhere
but, what's wrong with learn another different language and use it? Learning another language helps you to understand another cultures and be more open-minded. Don't expect immigrant to learn English immediately and forget their own roots. Nobody is forcing you to speak Spanish but you should know that speak the second language spoken in the USA could help you a lot. Do you want English to be the language of mankind? The world has learned English; although the truth is that in 2050 the USA will be the most Spanish-speaking country in the world.

PD: know that many us americans are open-minded and tolerant
Do not bother to write offensive and racist comments
To Whitney:
Please, express yourself I didn't mean that. It's just I don't wanna people to write offensive comments against latins or immigrants.
sorry!! please tell me what you think about this issue, I'm really interested in this
To mysterious maddness:
Don't be mad for that because in all of countries of the world is the same. You need English of course, but if you know another language much better. In Europe most people is bilingual, so it's almost obligatory to speak English and we aren't mad for that
To Bret:
I think you misunderstood me. I totally agree with you- latins must speak English and I don't think that everybody in USA should speak Spanish. I don't know what happens in Quebec but in Europe, American and English people always speak in English and if someone tell them something in the native language of the country, they get angry; believe me, it's that, I'm not wrong, English-speaking countries want the world to communicate in English
To safety pin:
Worldwide nowadays the term Latin refers to the inhabitants of Latin Europe, which draws from the culture left there by the Roman Empire, thus including the use of a Romance language, and Roman Catholicism. The term "Latin" may refer to the inhabitants of Latin America, which was colonized by different Latin European countries. Much of the population of Latin America are descendants of "Latin" peoples of Europe, and are either of pure or mixed ancestry
