“Her brain was incapable of feeling pain, pleasure, or anything.” If you know this is a lie then you are part of the problem. It is definitely not the truth regarding Terri, so I prefer to see you for what you’re trying to defend. You’re a lying ghoul.
Anyone, on any side of the debate, claiming ‘conclusive’ knowledge of what was taking place inside this woman’s head when she died is -at the very best- making educated guesses. There is a very good chance that Terri was incapable of ‘feeling’ anything, as indicated by her autopsy report. There is a very small chance that she was capable of feeling everything. Either way, no one knows conclusively and to claim to know the ‘truth’ is facetious.
