Yeah but I'm talking about the tradition, the protocol, the etiquette (if there is such a thing) of the office of the president. Are those things sacred? Like in our Parliament, there are certain things that politicians will always do regardless of their personal view/ego because it is the done thing, the tradition. They would not get away with riding roughshod over the institution. I'm just amazed at how easily Trump has managed to burn the whole thing down in just 4 years.
I wouldn't used sacred to describe them. They are simply accepted norms of how outgoing and incoming administrations have interacted with one another over decades. Trump obviously doesn't care which rules or norms he violates. Beyond that, the public are more interested in dealing with COVID and paying their bills, than they are about the transition.
