The most identifiable origins of Immigrant intolerance and hatred stem with three groups that comprise what should be called the “Tanton Triumvirate.” – FAIR, the Center for Immigration Studies, and Numbers USA”.
Wikipedia describes (the recently deceased) Tanton thus:
John H. Tanton (February 23, 1934 – July 16, 2019) was an American ophthalmologist, white nationalist and anti-immigration activist. He was the founder and first chairman of the Federation for American Immigration Reform (FAIR), an anti-immigration organization. He was the co-founder of the Center for Immigration Studies, an anti-immigration think tank; and NumbersUSA, an anti-immigration lobbying group. He was chairman of U.S. English and ProEnglish. He was the founder of The Social Contract Press, which publishes the quarterly journal The Social Contract. He founded the pro-eugenics organization Society for Genetic Education.
Although his groups have become accepted by the mainstream as a legitimate side of the debate, consider Tanton’s actual views. A few quotes reveal Tanton’s thinking on immigration:
“I’ve come to the point of view that for European-American society and culture to persist requires a European-American majority, and a clear one at that,” he once said. “.Do we leave it to individuals to decide that they are the intelligent ones who should have more kids? And more troublesome, what about the less intelligent, who logically should have less? Who is going to break the bad news [to less intelligent individuals], and how will it be implemented?”
The Tanton Triumvirate (FAIR, CIS and Numbers USA) exert an outsized powerful influence over the White House – maybe more than any three groups on this issue. They are often consulted and quoted when the President and his Senior Advisory for Policy – Stephen Miller – consider the White House policy on immigration.
They produce research which is rarely subject to any serious peer review that purports to show the damage that immigrants (illegal and legal) do to America. Often this research is childishly one-sided and shoddy, but nonetheless their research has influenced the talking points on immigration for decades. It is this flood of untruths, half truths and thinly veiled racism that has reached the ears of Crusius and millions of others. Trump is another pawn of the Triumvirate’s game.
