The circumstances are most likely something like this: the danger of the virus is being overhyped, the dangers of the vaccines are being downplayed, the efficacy of repurposed cheap old drugs including ivermectin is being suppressed for the sake of profits.
The result is, healthy young people who almost certainly cannot benefit from taking the vaccine are being pressured to take it, suffering extreme adverse side effects, and being told that they're just psych cases (suffering from anxiety or something similar)
Here's one example of thousands: https://www.youtube.com/watch?v=aebtcTi7EaA Healthy young guy, professional athlete, took the vaccine when there was no need for him to. Now he suffers from excruciating pain, has to flop out of bed in the morning to try to gain mobility, almost passes out when he stands up, etc.
Here's another example, a guy reporting 25,000 comments about adverse reactions in Israel. This used to be on YouTube, but it was censored there. https://odysee.com/@TheInformer:1/avibarak:1
Here's a doctor in California writing to the FDA and CDC about personally seeing far too many adverse reactions for the official numbers to be correct. https://www.sirillp.com/wp-content/uploads/2021/10/Letter-Re...

I could go on and on. The point is, people are seeing that things do not add up. The things they're personally seeing and hearing are not matching what they see from the MSM. Nobody likes being lied to. Nobody likes being stonewalled when people are dying. That's where the resentment and anger comes from that fuels the threats. Again, the threats are wrong. But what does any cornered animal eventually do?
