Pentti Linkola

If there were a button I could press, I would sacrifice myself without hesitating, if it meant millions of people would die. Pentti Linkola was a writer, ornithologist, fisherman, and radical environmentalist from Finland. The hardest of the hard greens, he believed that human population should drop to a small fraction of its current numbers to curb consumerism.

Specific views
Linkola advocated eugenics and praised the idea of World War III as a depopulation measure, and in the same vein he defended the Holocaust:

And the 2004 Madrid bombings:

Asked why he wasn't a terrorist himself, he simply admitted that he lacked the bravery and skill.

Linkola opposed democracy, comparing it to a free-for-all in a huge supermarket, and said that he preferred dictatorships, as they are reigned by other values than consumption. He strictly opposed not only immigration, as it tends to increase consumption, but also education of women in developing countries, again for the same reason.

He did not refer to himself as "hard green", but instead he described himself as a "deep ecologist" in Can Life Prevail?, the first of his books to be published in English.

Linkola was an atheist and opposed Lutheran Laestadianism in particular. Laestadianism forbids contraception and its followers usually have large families, which Linkola thought should be criminalized. He was also supportive of conscientious objectors.

Linkola's fansite includes a link to an alt-right website called amerika.org, which displays radical environmentalist views of the "blut und boden" type, although it seems rather dissimilar with the ideas of a man who cheered on Europeans dying in Islamist terrorist attacks and liked fascism specifically because of all the First World people who died as a result of it.

Influence (or lack thereof)
Pekka-Eric Auvinen, the perpetrator of the in which a total of nine people perished, was a fan of Linkola's texts and quoted him several times on his website he left behind. Linkola claimed Auvinen to not have been particularly motivated by him:

Linkola's international reach has been limited by the fact that he didn't know English, so his thoughts have been mainly promoted by followers and through translations instead.

Comparison to Unabomber
Linkola is often compared to Unabomber (Theodore J. Kaczynski), an American terrorist, who attempted to contact Linkola by letter in 2014. (Linkola never read or replied to any correspondence sent in English and he made no exception in this case.) While the similarities in their views are obvious, they are by no means equivalent:


 * Both "retired to nature" from academia, which is an obvious commonality. Kaczynski was a hermit and a recluse, who rejected society, had no family, and lived alone doing odd jobs. Although such claims are often mistakenly attached to Linkola, Linkola was gainfully employed all the time, had a wife and kids, was very sociable and fun company to be with, and even had affairs with multiple women.
 * Kaczynski got his manifesto published only by coercion, while Linkola was an accomplished author and speaker.
 * Kaczynski framed his quest as a quintessentially American "struggle for freedom and individual liberties". Linkola had absolutely no problem with restricting personal freedoms and openly supported a fascist dictatorship that would enforce his Green policies.
 * While both are known for their radical anti-technology stance, Kaczynski is mostly concerned with the social impact of technology, while Linkola was concerned about the environmental impact.
