The Unabomber was not insane. And he didnt murder even 1/10,000th of what the real Obomber did. They tried to make him plea insanity to which he at 1st declined, but then eventually had to, otherwise--'lectric chair, burn baby burn. No, he had a cause, so to speak, a rebel cause: against high tech military/industrial materialism, which he(and others) figured was destroying the planet. Well, he has this super hi IQ, 170 or so, he was a math genius and taught in prestigious colleges on both coasts, but he just decided to take it upon himself to save the planet and people and such.
Sooooo, he moves way up in the backwoods in a tiny shack, and figures he gonna blow himself up some bad bad technocrats and professors and capitalists and such who were key figures along the military industrial intellectual or business pipeline. And he proceeded to do just that, for several years, with an extended hiatus in between so as not to be discovered.
He was what is known as an Anarcho Primitivist, feeling mankind should get back to their wild natural roots and live like hunter gatherers again. Sort of like a Jeremiah Johnson version of Drumpf, w/o the cotton candy hair and billions--taken us WAAAY the hell back--when humanity was simple and great, and pretty near like apes! If you asked if he wanted to bomb us back into the Stone Age, the answer would be, 'yes'.
Oh, small thing. He had written this Manifesto re his entire outlook on everything and it really a brilliant pc of work that everybody would do well to read. And he called up a newspaper and said he'd stop the bombing if they published his Manifesto, which they eventually did, so he stopped the bombing.
Well, they finally caught him as per one of his brothers snitched on him and to this day he still sits in prison. So, the moral of the story is: he had alot in common with Obomber and Drumpf.
