A single person reacting that way is unlikely to make the speaker liable, but when a large crowd reacts the same way and the speaker does not make attempts to defuse the situation, then liability should be assigned.
So you’re saying that every supportive observer in every worldstar fight video should be held liable for any injuries? Not suggesting you’re wrong or right, but your approach places a novel legal burden on observers, and thus detaches it from actors, where the responsibility currently lies.

Not at all - I'm saying the liability should go in the opposite direction. If worldstar fight videos incite lots of people to start fighting in the streets, then worldstar should be partially responsible unless they take actions to distance themselves from their viewers' actions.
