"Progress" hasn't been a constant and physical control of people has been limited (again thanks to 2A). Lay the legislative foundation of medical choice being the gov's business and it will indeed get slippery. Way too much incentive for it not to. Add in disarmament where faceless/nameless bureaucrats can make these decisions and use the force of gov.

I was saying all some parties have to do is call a thing "child abuse" and all of the things you said won't happen will happen to a person. Those could be real consequences.
