Straw man argument.

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.
