The papers in the Bentley Library also show that Tanton has for decades been at the heart of the white nationalist scene. He has corresponded with Holocaust deniers, former Klan lawyers and the leading white nationalist thinkers of the era. He introduced key FAIR leaders to the president of the
Pioneer Fund, a white supremacist group set up to encourage "race betterment," at a 1997 meeting at a private club. He wrote a major funder to encourage her to read the work of a radical anti-Semitic professor — to "give you a new understanding of the Jewish outlook on life" — and suggested that the entire FAIR board discuss the professor's theories on the Jews. He practically worshipped a principal architect of the Immigration Act of 1924 (instituting a national origin quota system and barring Asian immigration), a rabid anti-Semite whose pro-Nazi American Coalition of Patriotic Societies was indicted for sedition in 1942.
Tanton also runs the racist publishing company,
The Social Contract Press, which is part of his foundation, U.S. Inc. One special issue of the press’ journal, The Social Contract, was devoted to the theme of "Europhobia: The Hostility Toward European-Descended Americans" and featured a lead article from John Vinson, head of the Tanton-backed hate group, the American Immigration Control Foundation. Vinson argued that multiculturalism was replacing "successful Euro-American culture" with "dysfunctional Third World cultures." Tanton elaborated in his own remarks, decrying the "unwarranted hatred and fear" of whites that he blamed on "multiculturalists" and immigrants.
In 1994, The Social Contract Press republished an infamous racist novel,
The Camp of the Saints, along with his wholehearted endorsement and a special afterword from its author saying "the proliferation of other races dooms our race, my race, to extinction." The novel describes "swarthy hordes" of Indian immigrants who take over France, send white women to "a whorehouse for Hindus" and engage in a grotesque orgy of men, women and children. The immigrants are described as "monsters," "grotesque little beggars from the streets of Calcutta" and worse. Unconcerned, Tanton said he was "honored" to republish what he described as an important and "prescient" text. The novel, like the race war fantasy
The Turner Diaries, has become a key screed for American white supremacists.
