As far as the %26quot;radical environmentalist%26quot; clarification by Idoni, many radical movements are not based in defensible logic. There is almost a sense of mysticism in any radical movement that takes a small nugget of truth and runs with it, regardless of others facts. Just look at religious Christian radicals waiting for %26quot;the end times%26quot; in their lifetime or Muslim radicals wanting to blow themselves up so they get 70 virgins in the afterlife. If is very difficult to reason with anyone that is radical, regardless of the topic.
