No man or woman can use his or her God given freedom to take away the freedom of another because that freedom was not ours to take away. <The foundation of what is justice.
That's fine and dandy and swell. But it's still the Constitution, not the Declaration, which is the social contract of our nation.
And like I said, in this case there's no need to appeal to the Declaration. The Constitution protects the right to life (which, as I recall, was the subject of this thread...) in Amendments 5 and 14. What more do you want? Why would you rather point at the Declaration than the Constitution? I don't get it.
