You're exactly correct. That's why the regression to the primitive never has a stopping point: they're never satisfied, unless humanity is dead. Ultimately in their philosophy any modification of the environment by humanity is bad, and humanity must modify the environment to survive (even at the most basic levels of agriculture, wood, fire, etc).

But you can go a step further: it starts with self-hatred, without exception that is where it always begins. That self-hatred is then projected outward as a more generalized hatred for humanity.
