All this shutdown of speech should underscore a few things:
1) Those men from the 1700's knew Freedom of Speech had to be a unoquivocable right. That means hate speech, disinformation, etc, etc, cannot be censored by the gov't. There are the obvious limitations, like fire in the theater things; but the USA was a country founded by ADULTS who acted like ADULTS and not a bunch of school kids reacting to "teacher, Johnny said my mom wears combat boots and that I have the face of a donkey."
2) That TRUE freedom of speech is what they're scared of, moreso than even guns at this point. If the were not scared of it they'd actually report the truth. Knowledge is truth and they want to keep the populace ignorant (just look at education policies).
3) Europe, to my knowledge, has no 1st Amendement like laws. Certainly, nothing as liberal (in classical sense) of interpretation of what can or cannot be said as The First Amendment.
