I think people do get a little picky with some adoption language but I think we can all agree there are just some terms that are unexceptable...such as: "Gave up", "illigitamate", "unwanted" etc.
I liked this site because it was very clear about all these terms as well as other scams and practices that should not be allowed.
Natural child: any child who is not artificial.
Real parent: any parent who is not imaginary.
Your own child: any child who is not someone else's child.
Adopted child: a natural child, with a real parent, who is all my own
