Im looking at the UN, haven't read it all- most is irrelevant- but there's 3immeidately that could inspire a debate by the anti's:
All human beings are born free and equal in dignity and rights. They are endowed with reason and conscience and should act towards one another in a spirit of brotherhood.
Everyone has the right to life, liberty and security of person.
No one shall be subjected to torture or to cruel, inhuman or degrading treatment or punishment.
but the Pro side (sorry, divide everything into anti and pro at Uni LOL):
(3) The family is the natural and fundamental group unit of society and is entitled to protection by society and the State.
Article 25.
(1) Everyone has the right to a standard of living adequate for the health and well-being of himself and of his family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control.
(2) Motherhood and childhood are entitled to special care and assistance. All children, whether born in or out of wedlock, shall enjoy the same social protection.
Its never simple, everything is just a debate really. And the USa don't really do the UN charter anyhow.
