Back when I was an Objectivist, Ted Kaczynski, the Unabomber, who "killed three people and injured 23 others in a nationwide bombing campaign against people he believed to be advancing modern technology and the destruction of the environment" (Wikipedia), was presented to us as the living proof of the "anti-man" (and literally homicidal) nature of environmentalism.
As a deep ecologist, I was wondering how far I would sympathise with the agenda of this "eco-terrorist", from whom Chad Haag tries to distance himself a little (though the subtitle indicates this is an uphill battle), and I was surprised to discover that if Kaczynski was indeed a terrorist, he may not have been altogether deserving of the prefix eco-.
Indeed, Kaczinski is a kind of radicalised Ellulian critic of technique (in the broadest possible sense) who seems much more concerned with what it is doing to us (i.e. turning us into machines ourselves), than with what it does to the environment. Based on the evidence presented in the book, I would say Kaczynski is more of libertarian terrorist, taking libertarian in both its political sense and its metaphysical sense: Kaczynski sees technique or technology as a threat to human free-will, and if there was some positive motivation behind his murderous acts, it seems to have been the defense of this free-will.
When the environmental consequences of technology are mentioned, they appear to be either after-thoughts (secondary arguments against technology, if the main one failed to convince you entirely), or worrisome only insofar as they threaten human survival (potentially leading to the disappearance of breathable air or drinkable water, for instance (p42) and of the human race itself (p253).) As for the animals, Kaczynski does not care much about them, though of course, they would immensely benefit from a world in which his Butlerian Jihad cubed was implemented. Kaczynski himself used to live by hunting for food, and is contemptuous of the vegan movement, dismissing the "alleged (!) oppression of... animals" as one of many "irrelevant problems" (p175) or "inessential issues" (p176.) Only the destruction of technology matters to him. The movement he intended to launch would not care about anything else.
While I did find Haag's anti-leftism refreshing (he has many interesting pages on SJWs and the left-wing mentality), I'm afraid he himself appears to belong to the lunatic fringe of the right. An outlaw himself (who fled the U.S. for India in order not to have to repay his student debt), he is fascinated by very strange figures indeed, including another terrorist, Vlad Vikernes, a black metal occultist who burned churches and murdered one man, but whom Haag considers one of "the most important writers of our era" (p156), along with the antisemitic madman David Icke, the originator of reptilian conspiracy theories. Haag himself seems to believe the Apollo program was a hoax, as he refers to "our supposed voyage to the moon" (p225.)
I'm not sure I will be studying Kaczynski's thought much further, but despite more than a few quirks, Haag does seem to have interesting things to say, and I will probably be reading his volume on Pentti Linkola, that other supervillain of environmentalism.
