Left–right political spectrum
The terms left-wing and right-wing are widely used in the United States, but as on the global level there is no firm consensus about their meaning. The only aspect that is generally agreed upon is that they are the defining opposites of the United States political spectrum. Left and right in the U.S. are generally associated with liberal and conservative respectively, although the meanings of the two sets of terms do not entirely coincide. Depending on the political affiliation of the individual using them, these terms can be spoken with varying implications. A 2005 poll of 2,209 American adults showed that "respondents generally viewed the paired concepts liberals and left-wingers and conservatives and right-wingers as possessing, respectively, generally similar political beliefs", but also showed that around ten percent fewer respondents understood the terms left and right than understood the terms liberal and conservative.
Ted Kaczynski
Throughout the document, Kaczynski addresses leftism as a movement. He defines leftists as "mainly socialists, collectivists, 'politically correct' types, feminists, gay and disability activists, animal rights activists and the like," states that leftism is driven primarily by "feelings of inferiority" and "oversocialization," and derides leftism as "one of the most widespread manifestations of the craziness of our world." Kaczynski additionally states that "a movement that exalts nature and opposes technology must take a resolutely anti-leftist stance and must avoid all collaboration with leftists," as in his view "[l]eftism is in the long run inconsistent with wild nature, with human freedom and with the elimination of modern technology." He also criticizes conservatives, describing them as "fools" who "whine about the decay of traditional values, yet they enthusiastically support technological progress and economic growth. Apparently, it never occurs to them that you can't make rapid, drastic changes in the technology and the economy of a society without causing rapid changes in all other aspects of the society as well, and that such rapid changes inevitably break down traditional values."
