Too much agency? Agency is what makes us human, (unless you think free will does not exist, which may be a defensible position, but that is a whole nother topic) so to deny them agency is to dehumanize them, which can only increase resentment. It’s a tough problem.
Fear is a powerful motivator, but getting vaccinated now is well, people will be getting sick between the first and second jabs then concluding that the vaccines don’t work. I fear what we are seeing is only the beginning of the shit show nature has locked and loaded. We will still be battling the SARS-CoV-2 virus as extreme weather resulting from global warming really sets in. Battered by two hoaxes at once! What fun!
