This was a pretty interesting article about Spanish not really likely to threaten the existence of the English language in the United States. It shows studies done, reflecting whether or not third generation Spanish immigrants still speak Spanish - much less whether they use it as their dominant tongue. It seems to be true, so far, that most 3rd generation Spanish citizens tend to lose their Spanish language, adopting English as their only language. Some still speak Spanish proficiently, or even fluently, but choose to speak English more often. Of course, I don't really remember bilingual education being so prominent as it is today. I don't know if that will affect language choices or not.
Though I don't agree as harshly as Newt does, I do agree that Spanish immigrants - - along with all other immigrants - - need to learn English. I don't think it would be wise to let Spanish share as a dominant language in our country. If we did that, other people from different ethnicities would want their language included as well. I think English should remain the dominant language of the United States. It has been that way for just about all immigrants. Why should it change, and why should other immigrants, who spoke different languages other than Spanish and English be required to speak Spanish? We need to maintain one dominant tongue.
If we don't, what would our road signs look like? We can't have huge road signs with everyone's native tongue written on them. How many languages are out there, anyway? People can't stop along the road to look for their language on a road sign, they can only glance. That would be a nightmare! We would have to have very long road signs, reflecting every one's native language. It would be much easier to just have English road signs in a country that has mainly spoken English for so long. I hate to say that we need to impose English on immigrants from other countries, but it has been that way since most settlers came from England. It's already scary to see that some people can't read the road signs today. I don't know how much of that is due to the fact that they don't speak English, but I am willing to say that quite a few can't read our signs because they refuse to learn English as the dominant language in the United States. What else will happen if many refuse to adopt English as their main language in this country?
