Everyone thinks they are good for laughs around here. Noone I know believes(or asserts) PETA has real power.
There are some groups, also w/o real power, who may have been considered dangerous. I have not heard of them being active recently. Mainly in western states.
Earth Liberation Front from 1997Welcome to the struggle of all species to be free.
We are the burning rage of this dying planet. The war of greed ravages the earth and species die out every day. ELF works to speed up the collapse of industry, to scare the rich, and to undermine the foundations of the state. We embrace social and deep ecology as a practical resistance movement. We have to show the enemy that we are serious about defending what is sacred. Together we have teeth and claws to match our dreams. Our greatest weapons are imagination and the ability to strike when least expected.
Since 1992, a series of earth nights and halloween smashes has mushroomed around the world. 1000's of bulldozers, powerlines, computer systems, buildings and valuable equipment have been composted. Many ELF actions have been censored to prevent our bravery from inciting others to take action.
