Those who advocate that the world is going to hell, do they point to a certain era as the most rational time, and what would have caused the downturn?

I'm referring to the reactosphere, of course, which I don't actually follow, but am aware of. Some trace the fall to the Enlightenment, some to the Reformation. Moldbug, on the other hand, has a lot of time for writers up to the 19th century, as people who knew what was what and from whose state of grace we have fallen. He has mentioned many times the persistent leftwards trend since then but the last I saw, still considered it a mystery. Others look to prehistory when men were men and women were chattels, and think that things started going downhill with the invention of agriculture, with the Reformation, the Enlightenment, and the 20th century being but further headlong descent down the rings of hell.

Leftists, in contrast, read the persistent leftwards trend as the inevitable march towards truth. At least, when they aren't crying "help, help, I'm being oppressed!", which requires portraying their opposition as the ones with power.
