Thanks for your post. The one thing you didn't address is my suggestion about folding into the new, "religious liberty" claim, an argument that she has a religious-based right to be divorced from a man who is openly flouting Catholic teaching by flagrant adultery and fathering illegitimate children.
Regretably, I don't see the "religious freedom" argument going very far given the current "freedom from religion" atmosphere.
The only things I can really see helping Terri would be either (1) the impeachment of Judge Greer and his replacement with an honest judge to hear the guardianship case, or (2) some additions to the guardianship statutes to expressly ensure that a judge can't order that a person be put to death before a pending guardianship challenge is heard.
