Jack also had an anarchist background. One of his tattoos, on his right leg, was a black and orange star, which was a symbol for an anarchist group. He had been vociferous for years online about his contempt for war and corporations. He'd written about these issues on his own personal web site, which he called gu.st, and also posted some rants about the perils of capitalism, his disdain for banking institutions, and Americans' thirst for oil. He also frequented message boards promoting feminism.
