Well I guess it's all how one defines "respect." I respect the office, and if I ever by chance met the president, I would give him the respect he deserves. However, with respect comes trust, accountability, competence, etc. I frankly don't think this administration has exhibited much of any of those qualities. Like I said earlier, I don't think it's fair to exaggerate by claiming the "worst in history," or even the "worst in my lifetime"
If you mean "respect" in the context of not making jokes surrounding his incompetency and failures, I disagree. Every president has been lampooned, made fun of, mocked, etc. It's part of American political culture and it's really nothing new to the American political discourse. Even when presidents have been popular, there will always be pundits who poke fun, mock, and make jokes about what they think is a failure or weakness of the chief executive.
