But they are artificial means.
I still cannot believe that God would want my body kept alive by machines, when it would die on its own.
You may disagree. I would not impose my beliefs on you - that is between you and your God.
When I lost my right to life in deference to your desire for a right to die, your beliefs were forced on me. There was a time, not very long ago, when the right to life was recognized, and the desire for life was understood. You could forfeit your rights by putting it in writing, but they couldn’t be taken from you on the assumption that you didn’t value your life as most people do.
