“This bears on the question of silence. If you are powerful, you sometimes have the ability to silence the speech of the powerless. One way might be to stop the powerless from speaking at all. Gag them, threaten them, condemn them to solitary confinement. But there is another, less dramatic but equally effective, way. Let them speak. Let them say whatever they like to whomever they like, but stop that speech from counting as an action.“
-Rae Langton, Speech Acts and Unspeakable Acts, 1993
