As Members of Congress, we swear an oath to uphold the United States Constitution. It means something to be an American because we believe in our country, we believe in our people, and we believe in our constitution.
Oaths are the fossils of piety.
People can and do change.
Cursing is invoking the assistance of a spirit to help you inflict suffering. Swearing on the other hand, is invoking, only the witness of a spirit to an statement you wish to make.
