Well no, you're well within ethical bounds to go after your son's bully, in your absolutely horrid and rare(!) example, but not for violence.

And it's not that dictionaries dictate our lives or courts have worked out what is and isn't illegal, it's that we can't coexist or communicate if people pretend words mean things they don't. More importantly: not everything that's bad and horrible is therefore "violence."

Another nuance: SimpleStacker steps in fron of you and pulls out a sharp knife. Give me your money (well, you know, 🌽). You hand them over and Stacker is on his way. Violence? Sure. While no punches or stabs delivered, the credible threat of stabs is definitely violence.

Is there an analogy to woke college students feeling unsafe when exposed to "dangerous ideas"? Nope. Is your example of child suicide closer? Sure.
