From the Boston Globe's "In Mexico visit, enmity greets Harvard scholar":

Ever since the release earlier this year of his book "Who are We?: The Challenges to America's National Identity," (excerpt online here)which argues that Mexican immigrants pose a threat to American culture, Samuel P. Huntington has been the US academic Mexicans love to hate...

The Mexican press seized on remarks he made Tuesday during a panel discussion at a three-day business conference in the [Mexican state of Veracruz], depicting him as alarmist and anti-immigrant. "Illegals: terrorist threat: Huntington" ran a frontpage headline in El Universal, the country's largest daily. Cronica, another Mexico City daily, led its culture section with a quote attributed to Huntington: "Mexicans could transport weapons of mass destruction."

...The governor of Hidalgo State, Manuel Angel Nunez Soto, called Huntington a racist, while challenging the facts behind the Harvard scholar's thesis that Mexican immigrants receive more than they give back to the United States. And Jesus Silva-Herzog Marquez, a political columnist who participated in a panel discussion with Huntington, described him as "the Stephen King of political scientists," in reference to the dire predictions of his recent books...

Huntington was more concerned by the way he said the Mexican press had misquoted him to suggest he was singling out Mexicans as posing a terrorist threat. Instead, he said, he was noting the potential of a terrorist attack perpetrated by people sneaking into the United States through the porous southern border with Mexico...

..."I think Huntington makes us see our own stupidity, like the prohibition against McDonald's in Oaxaca," [Silva-Herzog] said, referring to a recent campaign to block the American fast-food chain from opening a new branch in one of Mexico's most historic cities. Silva-Herzog challenged Huntington to propose solutions to the alleged threat posed by the higher birthrate of Hispanic immigrants, as well as other perceived problems. Huntington cites figures showing Hispanic women have an average of three children, compared with 1.8 for non-Hispanic whites and 2.1 for blacks. "What does he recommend? That they sterilize the Mexicans? That they prohibit Spanish from being spoken on the street?" said Silva-Herzog.
