You have no right to starve anyone to death. No matter what her state of consciousness is.
She's dead. There are a few ways to decide if someone is dead and and brain activity is one of them. On her EEG she has no activity and she is down to primitive reflexes where her brainstem is the only thing intact. She shouldn't necessarily be starved to death but instead taken off the feeding tube and given a morphine drip that is absolutely humane in this instance.
There are no longer any "moderates" on this issue, there is no political middle ground. I imagine that many people, including some here on this forum, will ultimately end up changing their party affiliation because of this. Life is now the defining ideological issue of our time.
The Republican Party was formed 150 years ago in the defense of subjectated human beings and tonight reaffirms that commitment.
