I've talked to leftwing people who fetishize small village communal living to the point where they have a belief that that's the only system that can work. Not quite anarcho primitivism, but definitely technoclast and anti-city.

I try to ask them about how we will get to this system that requires like 50% (or more) fewer people in the world, while pointing out that they will have to die, they say that they're not advocating for their deaths. But like, yeah you are, by ignoring the transition from lots of people to few people, you're not working to keep safe humans that are living!!
