Elsewhere in the world, only retroactively - in retellings, in legends, in K12 history lessons. The nice, patriotic fiction of good person saying something, galvanizing the population, and then large changes happening.

It's not. Broadcast media are barely 100 years old. The ability for any rando to broadcast thoughts outside their direct social circles exist for less than two decades.
Randos telling other randos within their social circles that they want bad things to happen to public personas - that is a cultural and historical norm. Nothing ever coming out of it, except maybe said randos landing in shit if the word reaches the public personas - that too is the cultural and historical norm. For such talk to be an actual danger to anyone else, and especially the subject of discussion? That is a very recent historical and geographical aberration (or rather, I suspect believing such talk to be dangerous is the aberration).
