My Notes

Dog-whistle politics
I use the Xholon BroadcastService to send messages to all people, but only some of these people react to them.
I use the new SIG_BROADCAST_TO_CHILDREN_REQ signal.
 - Send a regular async message to each child of each node in a list of broadcast receivers, but NOT to the broadcast receiver itself.

    Dog-whistle politics is political messaging employing coded language that appears to mean one thing to the general population but has an additional, different or more specific resonance for a targeted subgroup. The phrase is often used as a pejorative because of the inherently deceptive nature of the practice and because the dog-whistle messages are frequently distasteful to the general populace. The analogy is to a dog whistle, whose high-frequency whistle is heard by dogs but inaudible to humans.
