South Carolina cites, loosely, but with substantial accuracy, some of the language of the original Declaration. That Declaration does say that it is the right of the people to abolish any form of government that becomes destructive of the ends for which it was established. But South Carolina does not repeat the preceding language in the earlier document: 'We hold these truths to be self-evident, that all men are created equal'.
