What irks me is the people who are so positive they want to be seen off the globe in this manner should they lose the ability to communicate, that they want a system making it easy for Terris to be likewise drug to their death. Why shouldn't the onus to indicate their wishes be on those who want not to be "saved" by being given food and drink. Anything less is asking for people who never wanted it, to get starved and mummified.
Because they don't expect to be the ones tortured to death. Among those who have revealed their motives behind supporting forced euthanasia, all of them have in the past, and/or plan to in the future have someone else euthanized. We can only guess as to the motives of those who haven't revealed them.
