The only thing I can think of that the government can do is to clamp down hard on violence, including speech which advocates for violence (e.g. glorifying Luigi Mangione, calling everyone a Nazi/fascist, etc.). Freedom of speech ends where it actually turns into violence.
Reducing rights to speech that advocates for violence makes some sense, but what I'd like to see is reducing the lies and disinformation. Install a duty of candor to everyone who speaks in greatly public ways
