I'm sorry about your sister. I'm sure it's one of the most difficult decisions a family member ever has to make.
There have been many before her. We are moving into a utilitarian society. Those who brought out the PVS diagnosis and began slapping it on severely disabled people right and left, some of whom were using wheelchairs ( and were still condemned by a court to deliberate dehydration because they also used a feeding tube), are now speaking of new things.
They are speaking of less disabled people, conscious and alert people, and how their quality of life is so low that they, too, should be "allowed to choose the right to die".
They are talking about depression as a legitimate reason to die.
They are talking about children in the ICU at Boston Childrens being taken to the OR and having their organs harvested while they are still alive, and then dying on the table. Children with chronic pulmonary diseases or children who are brain damaged.
They are talking about using people like Terri for medical experiments instead of animals.
These are all ominous signs which should be of great concern for all Americans. This is about a lot more than Terri.
