So the fact of their helplessness is good enough reason for you to allow them to be treated as property?
Terri got due process. Many courts heard hours of testimony and came to the conclusion that Terri would not have wanted to vegetate indefinitely. Obviously, her parents felt that they should have property rights over Terri so they could impose their will upon her. And now a bunch of nosy activists want to intrude into family decisions as well. They can sit down and shut up...it's not their business.
