Apparently, you have chosen to believe only one side.
The courts who have listened to the whole evidence do not find the Schinder side credible, while the courts do find Schiavo's testimony truthful.
I know that in these emotional issues there is very little room for rational debate, and I will expect you to keep repeating this mantra that only "he alone claims" Terry's wishes.
The fact that Terry's brother in law and his wife also testified in favor of Schiavo's claims can be easily dismissed and ignore, with the mantra "he alones claims."
It reminds me of a nasty divorce I witnessed first hand.
The wife accused the husband of child abuse, and she produced the affidavits and testimony to support her case.
The husband accused the wife of raising the kids in a dangerous, deadly cult, and he also produced affidavits and testimony.
Eventually, the courts had to make a decision, and both claims were found to be false and irrelevant to the custody issue. Nevertheless, the people who took sides believed the false allegations.
