i think where you and i differ on this is the issue of public safety. i think gov't has a responsibility to look out for the greater good. stopping the spread of life-threatening yet preventable diseases would be high on that list for me.
i appreciate you wanting to stop the spread of gov't reaching into too many areas of our lives, but on this issue i disagree with you completely. as someone with a propensity for lung problems, i don't want to be put in the position of having to fight off an infection that is going to cause me a lot of personal distress, especially if that exposure could have been prevented by something simple like an immunization for my students.
