Can’t talk for anyone else, but I put them in the same category as PETA.
They probably do a lot of good, but it feels like the good they do is outweighed by all the bad they do to get there.
Like kidnapping collared dogs from the streets to euthanize them (PETA), or fighting the (at the time) only realistic alternative to oil, giving all the rich oil sheiks a hard on and adding to the already bad global warming problem (Greenpeace).
