My wife is a Cuban immigrant. She read that article, and agrees with it completely. I agree, also--even though some might find the phrasing harsh. Immigrants should embrace the culture of the United States, while keeping those elements of their home cultures that give them identity. Language skill in English is not a cultural issue as much as it is an ECONOMIC issue. Non English speakers are doomed to the bottom level of the economic pyramid.
Why has it become so bad to express such an opinion? What is really illegal, immoral, or anti-anybody in that article? I say "nothing". One interesting thing I do find here is the Jefferson quotations by JB88, who would probably discount Jefferson's real ideals--slavery, gun ownership, suffrage limited to land owners, and other non-pc viewpoints.
I have been taught, and have read, and studied, that our country was founded on Judeo-Christian principles, with an injunction against State sponsored religion. Period. You can read the God word in every founding document, and most (but not all) the founding fathers were men of faith.
Show me where I am wrong.
