I mean, even the example used ("the noble class") is preposterous on face because:
1. The Russian Revolution? Germany 1849? Even the American Revolution? None of these are about ideas, or "shining the light on ignorance" -- they're about putting the nobility up against the wall. If there's some kind of teleology at play here, it's not that we thought about it in the marketplace of ideas long enough and decided to do away with the concept.
2. Nobility still exists! At best, this just means we live in a secular society, where we no longer believe the Word of God justifies massive inequality.
