Wow, that's a rude and (more importantly) factually incorrect remark. Is HN becoming Reddit?
Uh, your history classes have really failed you. These rights
weren't novel, they were explicitly enshrined in the English
Bill of Rights in 1689. Some of the other rights (particularly
debtors' rights) date back to the Magna Carta in 1215.
Sure. That's why I qualified my statement: "not entirely new" and "fairly novel" rather than "entirely novel" because I'm aware that the U.S. Constitution is not the first time these notions have appeared in law. It was specifically an attempt to head off a pedantic reply such as yours.
For the record, you're citing a 1919 US Supreme Court case
that has been overturned. The current standard for free speech
in the US is Brandenburg v Ohio [1], which holds that it is
constitutionally-protected free speech to advocate violent
overthrow of the government
You're simply incorrect. The justices' opinions in this case specifically agreed with this particular instance of prohibited speech, even referring to it directly.

Finally, Douglas dealt with the classic example of a man
"falsely shouting fire in a theater and causing a panic".
In order to explain why someone could be legitimately prosecuted
for this, Douglas called it an example in which "speech is
brigaded with action". In the view of Douglas and Black, this
was probably the only sort of case in which a person could be
prosecuted for speech.
More to the point, please understand: this ruling specifically addressed
inflammatory (no pun presumably intended) speech.
This was not a comprehensive ruling on speech in general. It was an influential ruling on speech specifically meant to rouse others to action.
There are innumerable other types of speech this ruling did not address. Libel, threats, etc.
Forget about folks' educations failing them; your misconceptions could have been avoided with a simple Wikipedia visit. On the bright side, this experience reminded me to make my annual donation to Wikipedia. Obviously it's a sorely-needed resource.
