It is not up to the state to say an undivorced spouse is no longer a spouse. Do you really want the government to be able to dissolve marriages without the knowledge or consent of the married adult couple?
It would have been a good thing in this one case, but a horrible precedent for the government to set aside legal marriages in the future.
Do you really want the state to initiate the death of a non-dying woman?
Do you really want a sick person to be judged as to whether or not they still are entitled to their constitutional rights as an American citizen?
Do you really want to allow SOME to write criteria that tells you when your relative cannot be considered worthy of life - as they are classed as a non-person in a state not worthy of constitutional rights, life, or further care?
