If this had been a matter of removing life support technology, I'd not contest it.Food, water, oxygen it's all the same you die without them. The controversy is the question of whether she is actually "here" or are they just holding her shell hostage using human technology. Seems others may have their own agendas also.
What gets me is that it's likely the same group that wants to artificially keep her "alive" that is tying the hands of the scientific community when it comes to genetic advances to preserve life. Am I wrong?
