Two problems with this. One, stupidity isn’t hereditary, and the parents who buy this load of malarkey aren’t the ones at risk. Two, poor herd immunity endangers children too young to have had certain vaccinations on their schedule even if they’re parents are vaccinating them, the elderly who’s immune systems tend to be weaker, the chronically immuno-compramised, and the temporarily immuno-compramised from serious illness such as cancer patients. In short, the kids of the anti-vaxxers, who to be clear don’t deserve to be thinned from the herd either, are only the most immediately at risk.
On top of that, epidemics and pandemics have numerous secondary social effects beyond the spread of disease, including but not limited to secondary or opportunistic diseases, job loss for the working poor, healthcare debt, psychological trauma, and the depletion or overwhelming of available medical services.
