FBI determines that leftist anarchists more dangerous than right-wing anarchists

The FBI has determined that so-called eco-terrorists and animal rights anarchists are more dangerous than right-wing militia groups and militant anti-choice groups. Though I speak as a person who is opposed to violence of any kind, I do find it more than interesting that the Animal Liberation Front, the Earth Liberation Front, and Stop Huntington Labs--groups that are violent against the material structures of corporations-- are feared more than people who murder doctors and kill children in daycare centers.
