The judge would not be 'imposing his will'. He would be respecting my will. Do you understand the distinction?
Suppose you are married, and your husband tells you that he would NOT want to be kept alive on a feeding tube for decades if something happened to him and he was in a PVS state. The worst later happens, and your husband is indeed rendered PVS. After years of hoping, you finally accept the fact the he is not ever going to get any better. Do you honor his wish to not be kept alive? Or do you keep him physically alive for as long as medically possible, despite his clear expression of his wishes?
You're being extremely dishonest. You know that Terri did not refuse food and water. Judge Greer decided that she would not be allowed to have food or water, through any means. It was his decision, not hers. Since you support his right to make that decision for Terri, why don't you support his right to make the decision for you?
