put another way, my interpretation of anarchism is not that people should be left free to lie, but that the infrastructure of the state should not be used to protect liars from the mob under the guise of "individual rights". that process of censure should be allowed to proceed, however violent it may or may not be.

right libertarians tend to get this backwards. they think that if you take the state out of the equation then there is nothing preventing them from lying for whatever profit or aim. they fail to realize that the status quo is such that the state actually protects them from the consequence of lying by erecting an immunity through rights legislation, and that if you take away these statist protections then they will have to face the consequences of their actions - which may be quite grim.
