If this is the case then these writers should be spending 95% of their words talking about how to go from here to a different better future, or even better rolling up their sleeves and attempting to live or create such a future here and now. The only criticism you need is whatever it takes to frame the problem. I’ve read Kaczynski and numerous other primitivists and reactionaries and that’s not the dominant theme. The emphasis is on a lost golden age (that I do not believe actually existed) and accusing modernity in a moralistic tone.
