Brain death is a term defined with legal implications. Your casual and erroneous use of the term in reference to Terri Schiavo reflects negligence and cripples any hope for credibility in your arguments.
The credibility that is lacking is in your arguement.
Whether using the term brain dead or PVS, which I think is the accurate medical term, you are on the losing side of this arguement.
I don't want to see Terri killed die and I'm sure doc30 doesn't either but it looks like that is what's going to happen.
If not this time then maybe the fourth time around.
