So, not much is changing then but you assumed history can only move forward. We’ve reached a point where this belief is pretty much a modern secular religion - nobody guaranteed it would be so. This religion even has prophets like Francis Fukuyama who I blame for popularising it.

It’s likely we will be set back again many times and there’s no guarantee that the end result will be satisfying. The best thing we can do for now is to figure out why those things happen in the first place without attributing blame. The future needs to include everyone, even the bigots. My guess most of the bigots wouldn’t be bigots if they had higher participation in profits that our societies generate. This is because politicians funnel those into the pockets of various oligarchs. Neither Republicans or Dems won’t fix that unfortunately.
