Just make sure your kids are vaccinated -- and then sit back and enjoy the ensuing Darwinistic exercise.
It's tough medicine, but maybe the only solution is to kill off a whole bunch of these idiots...
Sorry, Jay, but it doesn't work that way. Vaccines fail. Children get pertussis before they reach even the early weeks of vaccination. Even the vaccinated community is endangered by the anti-vaccine crowds. There should be no "crackpot" exceptions for school environments (Margy used to refer to her students as her little disease vectors).
