> You have no authority over someone else's body. It sucks, but it's reality. This is obviously untrue: the state can lock up and kill you, is currently asserting its right to restrict people from having abortions performed on them, and has been increasingly aggressive about attack peoples' right to undergo hormone replacement therapy, among many many other examples. Mandatory vaccination has very much been something the state has historically exercised its powers to enforce, quite successfully in the case of smallpox. We're extremely inconsistent about what authority we exercise over others' bodies, generally, but we're a very far cry from never exercising it or acting as if doing so were simply beyond the pale.
