Point being the ELF fit into a role that the media and the powers that be love, they play a role ideally suited to the antienvironemntal agenda.
Not because they give anyone a bad name, but because they are an easy stereotype that iconographically doesn´t challenge anything.
Earlier ecoteurs did not, sure later they fell into this trap - but simple, anonymous actions that are not draped in rhetoric or cliched imagery is imo far more effective and harder to dismiss.
The same argument could be made re their methods. Are roaring flAmes strictly necesarry?, You can (so I´ve been told

)stop machines etc. working in many ways that don´t provide stock footage for "terrorist" scare stories.
