Almost all of these look to be local-level disagreements or semi-organized crime, not radicalized teenagers on 8Chan.
The problem is that there is no such thing as "freedom of speech" it's BS, there is a right to have an opinion, but some opinions are crimes and should never become speech, let alone be public
Corollary: public speech must be granted to everyone, because it's in the US Constitution, but you should not use it to badmouth the US
No. The US does not criminalize thought, and doing so would be tyranny.
you should not use it to badmouth the US
Also No. The very purpose of freedom of speech and the press is to maintain channels for criticism and change.
Hard disagree here. Unless you're using some definition of crime I've never heard of, opinions can never be crimes in the US.
Even the advocacy of violence is constitutionally protected speech here.
