> Threats. That's one form of violence. Yelling "Fire!" in a crowded theatre, that's another.

Threat is instigating fear of injury. Violence is causing injury. You can have your own personal definition, but from a legal perspective, threat is not a violent crime.

Yelling "fire" in a crowded theatre isn't even illegal. Let alone a violence. Inciting panic is illegal. If you incite panic through yelling "fire" in a crowded theatre, you'll answer for inciting panic and will bear responsibility for the actual consequences, if any, not for the yelling.

Of course.

this violence is not confined to an actual assault of the person, [..] whatever goes to intimidate or overawe, by the apprehension of personal violence, or by fear of life [..] equally falls within its limits

That's pretty creative editing there. Everything you quoted (and omitted via ellipse) is prefaced by "In cases of robbery". The part about intimidation only counts when it is "to compel the delivery of property." Since this isn't a discussion about a robbery or theft or possession of property, the entirety of your quote is irrelevant.

Instead, read a little further: The term “violence” is synonymous with “physical force,” and the two are used interchangeably, in relation to assaults

Speech is not physical force, and is not an assault, and is not violence.
