I don't really care what the exact term in the statute is. Under Florida law, an "artificial" form of medical treatment can be terminated even if it causes the death of the patient.
I agree with you. Most sane people would not define artificial as food and water. This was obviously done to fit an agenda.
Where have you been? That's been the law in many states since the Nancy Cruzan and Karen Quinlan cases.
If you have watched someone die of cancer, you have seen this happen, even if they did not have a feeding tube. All you can do is stand helplessly beside them and try to put ice into their mouths.
