Often overlooked in commentary on anti-vaxxers, and by the anti-vaxxers themselves, is this:

Freeloading

The anti-vaxxers are freeloading on the herd immunity created and maintained by the smart people.

That herd immunity prevents the regular epidemics & pandemics common before vaccines, when families often had 10 children to see a few survive to adulthood.

There is plenty deliberate ignorance of history, Dunning-Kruger Syndrome, and confirmation bias in their 'arguments', but the root seems to be a (likely) unconscious willingness to freeload on the benefits provided by others.

This is unfortunately coupled with a deliberate ignorance of and/or willingness to deliberately endanger the small subset of people with bona-fide medical conditions that contraindicate vaccination, and so genuinely rely on the herd immunity to survive.

It is far past time to coddle this deliberate ignorance and freeloading. If anti-vaxxers want to stay that way, fine, but they need to choose and not be permitted poison the well - vaccination needs to be required for alk access to public buildings, schools, transport, etc.
