Fr. Bryce Sibley of A Saintly Salmagundi has two excellent Terri-related posts up: "Reflections on the Terry [sic] Schiavo Situation" and "On the Phone About Terri." "On the Phone" details what happened when he called activist organizations to ask their position about Terri's case, as when he called Amnesty International:
I thought for sure they would have made a statement since they are well-known for their human rights work. The woman I spoke to was very uncomfortable and said that they as an organization did not want to get involved. I pressed her and said they would probably get involved if children in Africa were being starved to death, but she could not come up with a response.
