If we oppose terrorist acts, it is only because individual revenge does not satisfy us. The account we have to settle with the capitalist system is too great to be presented to some functionary called a minister. To learn to see all the crimes against humanity, all the indignities to which the human body and spirit are subjected, as the twisted outgrowths and expressions of the existing social system, in order to direct all our energies into a collective struggle against this system—that is the direction in which the burning desire for revenge can find its highest moral satisfaction. -Trotsky

Individual acts of terrorism are bad and counterproductive. I find the people who idolize Ted are those too young to remember that most of the people injured by his bombs were postal workers, secretaries, academics, and airplane passengers. He might as well have been a CIA MK ULTRA sleeper agent for the damage he did to environmental/left-wing dissent to Capitalism.
