This is a good essay on Left Moldbuggism, and let me add that one reason many of us moved away from old fashioned Moldbuggery is that 10-15 years ago there was a widespread belief among us that American society was headed towards collapse due to unsustainable debt, changing demographics, and so forth. That was the basis on which to advocate radical change. The collapse will come, so be ready for something new.
In 2024, this is no longer credible. So all you’re left with among radicals is people who are so angered by transsexuals and changing demographics that these things alone are a reason to overturn the entire system. They generally are suffering from too much rage and anxiety, which makes it difficult for them to keep things in perspective.
