While the label is impolitic I have to side with Scalia on the underlying issue.
The claim of the living constitution proponents is our society is a changing one and the Constitution must change with the times. Yes, and the Founding Fathers accounted for that fact by creating an amendment process. This way the Constitution can be added to or subtracted from as societies changing needs demand.
What the living constitution proponents really want is a constitution that suits their personal political goals rather than that of the societies.
