A very good read on the immigration problem can be found at the Federation for American Immigration Reform (FAIR) The article discusses the idea that there are many folk that believe the southwest US does not belong to America, but rather it was improperly taken and should be returned to Mexico. Excerpt below:
A June 2002 Zogby poll of Mexicans found that a substantial majority of Mexican citizens believe that southwestern America is rightfully the territory of Mexico and that Mexicans do not need the permission of the U.S. to enter. The poll found that 58 percent of Mexicans agree with the statement, “The territory of the United States’ southwest rightfully belongs to Mexico.” Zogby said 28 percent disagreed, while another 14 percent said they weren’t sure.
The more radical of these shout: “Go back to Boston! Go back to Plymouth Rock, Pilgrims! Get out! We are the future. You are old and tired. Go on. We have beaten you. Leave like beaten rats. You old white people. It is your duty to die . . . Through love of having children, we are going to take over.” Hat tip to American Greatness for the quote.
