I found this extremely thought provoking. Imo it isn't exactly true. I don't think societies gravitate towards it as much as they slowly let it happen to them, like the boiling frog metaphor.
However I think it's 100% true for western civilization in modern times. Why? Imo there can only be one answer - it's being subtly taught via education and socialization.
Just a few generations ago we had family that literally got on boats with no guarantee of safe arrival, that set out across this land with no promise of safety, that charged beaches or other battle lines, etc etc. Yet now we're reduced to words are violence and npc like behavior.
It's equally sad, scary, and infuriating
