March 3: Firefighters battle a blaze in Woodinville, Wash.However, I would agree that bad things could happen and may happen due to the activities of this group either due to accident or someone may just decide to make a "louder/stronger" statement.
I think that the group: ELF use the propaganda technique of 'poisoning the well'. They think that all human activity is a plague on the earth. They are so committed to protecting the earth that they will not listen when a builder claims to be eco-friendly. They do not see how a luxury home can be built and be good to nature. They also use 'appeal to authority' because they feel that their authority establishes their claims as correct.
The FBI uses propaganda of spin words to paint the ELF group as a terrorist threat to all of America when it's clear that they are targeting the "rich". I've not heard of them burning down a trailer park and they are more of a harm to the earth than a luxury home is.
Is the group ELF dangerous? Obviously to our fancy homes they are. And since they also take credit for damage to oil pipelines, they could really mess up our comfortable lifestyles. But so far, I do not think we need to fear for our lives.
