I'll throw one out for COVID, but not just the lockdowns or the immediate work changes. It was more about how the deaths kept happening. And happening. And happening. Yet people still failed to take it seriously, even to the point of rebelling against seemingly common-sense safeguards like vaccines, masking, and staying the fuck home.

In the US, we lived through about 4 years of shenanigans and bullshit and lies from an incompetent federal government leading up to the pandemic. But surely that wouldn't fly for long. You can lie about the number of people at a rally (because who the fuck cares), you can apparently lie about where a hurricane is projected to go (because it's jUsT a PrOjEcTiOn or something), but surely you can't bullshit your way out of a pandemic. Hospitals at capacity. Bodies piling up. Loved ones lost. Visible, real, tangible impacts of poor leadership and poor decisionmaking.

But, turns out you can. Even in the most dire of circumstances, you can still convince people that reality isn't real. Or even if it is, it doesn't really matter and it's not their problem. And there are enough people out there who will buy into that message that it will ruin things for everyone else.

Edit: To the original point of the question... I guess I had a little more faith in humanity before all that happened. More faith that real-world consequences would win out against rhetorical bullshit and tribalism.
