Half of jurisprudence is grounded not in writings that came after the Revolution, but English Common Law. We lean on the First Amendment for issues of free speech, but we lean on the Magna Carta for questions of whether you've produced the right magic slip of paper to prove you own the land your outhouse sits on.
... hell, many of the states have a right to grant exclusive ownership of that land that's fundamentally rooted in a king having granted them that right.
And that's just the tip of the iceberg. You can't ignore that we're mostly speaking English for some reason...
It isn't. Learn your history.
With respect, between the work of a Cornell professor and an internet rando, I'm going to defer to the professor on the topic the professor wrote on.
The CCP has no continuity with the previous imperial government. They love to make that claim when it's convenient but it's bullshit. It would be like the US claiming they have a national continuity with Britain going back millennia.
