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.
you might have some blind spots yourself though. the biggest set of spiritual sickness and violence are whats happening to immigrants by ICE, and the support americans are giving to israel to do mass horrors to gazan civilians.
theres tons of violence going on thats much more current than talking about luigi or calling somebody who is a fascist a fascist
