Ahh OK. So would i be OK with someone doing something to me or a loved one against my wishes? No, but would i give blood in this case if it was a law, yes. Laws force you to do something potentially against your will.
Someone is driving a car swerving, driving erratically, and when the officer pulls them over the car smells of alchohol. The officer requests they do a breathalyzer or they go to the station for a blood test, refuse that and they lose their ability to drive for a year. They refuse everything, is it fair the officer can force them to not drive and take away their free will for a night throwing you in jail?
If that isn’t the same thing fine. What about required vaccinations before a kid can go to public school? That policy is recently under more scrutiny since covid. For the greater good i think that is a good policy.
