The front line nurses who were heroes a year ago, are now hated... until they become homeless, and we'll feel sorry for them again.
Effectively zero people are angry with those who cannot get vaccinated for valid medical reasons.
People are angry with those who claim "medical reasons" as to why they cannot be vaccinated, when they are lying.
I cannot receive certain vaccines due to legitimate medical reasons: however I can and did receive the COVID-19 vaccine.
Those who cannot be vaccinated need herd immunity to be protected. People who lie and claim to be a member of that small community of vulnerable people put those same people at massive risk by making herd immunity impossible to achieve.
But you know all this already, none of this will convince you.
Maybe people think talking about unvaccinated people here is irrelevant or inflammatory or something like that; I don't know what exactly ties these stories together in my mind, but I suggest that maybe it's technophilia, that there are people who love to throw technology at every problem. Or, perhaps the hate comes from the sense of certainty some people have in their information sources, and they can't empathize with anyone who may be suffering from false or ideological info sources. Instead such people must be stupid and trolls.
If it is a lack of empathy -- I think it's more likely a lack of sophistication -- I can see this same mode of hatred and blame we are seeing now, being directed at criminals back when those draconian laws were being drafted that put the deaf man in jail.
