I have spotted this totalitarian streak among some of my friends who went to med school. We should ban smoking, force everyone to do this or that. As bad as they can be, we're probably better off with lawyers in charge.
People die because some idiot parent didn't vaccinated their children, so I say yes, enforce it or don't live in society, go to some isolated island because you are causing harm, it's as totalitarian as allowing people to play Russian roulette with other people's children (actually you'd go to jail so I think we're too lenient with these parents).
i understand if someone doesn't want their child vaccinated and they can't go to public school, but forcing people is another thing, even if it is 'for their own good'.
