You have to take things in context, though. Certainly, if the Founding Fathers showed up today, with no knowledge of what has happened over the last 230 years, they would be appalled. The clothing (Franklin would love the bikini’s though), the music, the cars (!), the architecture, etc alone would be quite a shock.
These were wise men who understood that things change. John Adams would probably be the most vocal and read congress the riot act. Washington would want to oversee the war. Jefferson would try to get the White House organized. John Hancock, perhaps the most patient man in the Continental Congress, would take on the role of teacher and try to reducate the government on their jobs. John Dickinson would go after the Supreme Court.
