I think the parents made a big mistake in not trying to get her divorced
I think Mr. and Mrs. Schindler tried to get a divorce for Terri, but the corrupt FL judiciary blocked them at ever turn. They have never received justice in FL. I am pretty sure that they will leave that corrupt state after Terri dies. Surely they must forever regret moving to the "Land of Sunshine."
If Terri had ever made mention that she would not want to be kept alive by artificial means, her frame of reference would have been Karen Ann Quinlan, kept alive on a respirator.Feeding tubes were not considered artificial means at that particular time; therefore, she could not possibly consent to something that wasn't in existence.
