Punishing families does not save lives.
It is, of course, a tragedy that kids die from "preventable" diseases. You use the word "preventable" without really defining what it means, and in the context you are using this word it doesn't quite make sense.
We are talking specifically about the case where a small number of families refuse to get their kids vaccinated for religious or philosophical grounds.
There are two ways of dealing at this problem.
1) We can be punitive. We can apply penalties and make life as hard as we can for people who don't submit. Of course, the penalties we inflict are going to cause hardship for families and for kids.
2) We can accept that after a well-run public education campaign with widely accessible vaccines there will be still be few families that still don't want to have the vaccines.
Now Boomerang, I get that there are tragic anecdotes of dying kids. But they are not relevant unless you can show that punishing kids and families saves lives. And the stories of death you tell accentuated with italics don't explain at all how punishing families
would have made any difference.
The science says that after a certain rate, the last percentage of kids you vaccinate doesn't make a difference. In this case we are punishing families just for the sake of punishing families.
