I get the distinct impression that most of the people who hate nihilism or (non-primitivist) anti-civ thought don't ever actually bother engaging with them. Or, if they do, they assume they couldn't possibly be nihilist or anti-civ, because those things are Bad.
Not to say I entirely blame them, it's not like I'd ever seriously listen to, e.g., Nazi ideas. But I feel like a lot of people who say they hate nihilism and anti-civ thought would, if they weren't told what they were in advance, be totally fine with stuff like "Locating an Indigenous Anarchism" and "Desert"
