Yes, Derrick Jensen is something of an asshole (check out some of his rants about anarchists and transgendered people if you don’t believe me). No, I don’t buy his claim that the only viable alternative to civilization is stone-age tribalism.
But, that said, the guy (and his co-authors) does have some valid promises about this civilization being so destructive that it must be ended, the sooner the better, in part because the official mechanisms of power are pretty much useless for the purpose of arresting and reversing the destruction.
Update: Note that this endorsement of the book with the title Deep Green Resistance is not an endorsement of the organization by the same name. The latter appears to be dominated by a cult of personality around Derrick Jensen as much as the Revolutionary Communist Party is by a cult of personality around Bob Avakian.
