DENVER - Parts of the manifesto written by the suspect in Norway's terrorist attack were taken almost word for word from the writings of "Unabomber" Ted Kaczynski.
The passages copied by Anders Behring Breivik appear in the first few pages of Kaczynski's manifesto. Breivik changed a Kaczynski screed on leftism and what he considered to be leftists' "feelings of inferiority" — mainly by substituting the words "multiculturalism" or "cultural Marxism" for "leftism."
For instance, Kaczynski wrote: "One of the most widespread manifestations of the craziness of our world is leftism, so a discussion of the psychology of leftism can serve as an introduction to the discussion of the problems of modern society in general."
Breivik's manifesto reads: "One of the most widespread manifestations of the craziness of our world is multiculturalism, so a discussion of the psychology of multiculturalists can serve as an introduction to the discussion of the problems of Western Europe in general."
