I think people should have the right to choose. That being said, every choice has consequences. Let the parents choose, but close the loophole that allows non-vaccinated kids to go to school. In fact, expand it to make it illegal (child endangerment) to take your non-vaccinated kid pretty much anywhere that would reasonably expect more than 10 or so people to gather.
No restaurants, no grocery stores, no JetBlue flights, no schools, no pre-schools, no churches, no emergency rooms, nothing.
Keep your little petri dish kids in their rooms.
