Putting history in context is not taking a stand for any particular historic institution. The institution I would, and will defend, is the pledge to one another of the signers of the Declaration of Independence; also the Constitution to which some of the same men contributed 11 years later. Oh, one other. The Founders' commitment to truth.
Your parcel of sanctimonious hate spewers might not understand; but your intention to pass judgment on earlier generations of American leaders violates the spirit of the heritage you pretend to honor.
