No REAL historian would say any such thing...particularly given the background and copious writings of the Founding Fathers and/or signers.
A REAL historian would have looked closely at the development of the phrase and known that it was the subject of great discussion - that “property” was preferred by some to “pursuit of Happiness”. The connotation property perhaps having a wider meaning than today, but was determined to be subsumed by the term adopted. Liberals would never want anyone to understand the ramifications of the original intent. Today’s Government would never let one think that they can actually have a property right not subject to the Governments ability to take it.
