According to speech-act theory, we do things with words every time we speak. The most striking thing one can do with words is to exercise authority over others, such as when a judge issues a guilty verdict in a criminal trial. Some speakers hold this kind of authority without good reason; this kind of speech constitutes an unjust imposition of authority, and thus arguably harms in a direct, non-metaphorical sense; it would seem, therefore, that it should not be protected by freedom of speech. The problem in these cases, however, does not lie in the words that harmful speakers utter, but in the things they have the power to do with them. It is this power, it seems, that must be dismantled: in speech-act terms, we must tackle felicity conditions, not locutions. This paper defends this insight. By providing an account of the (alleged) authority of pornographers as both epistemic and informal, I claim that the presumption against censoring porn is not lifted even if the speech-act argument succeeds in showing that pornography can be constitutive of harm. This does not mean that such harms should not be countered, but they should be countered as the specific kinds of harms that they are.
