…our discourse is shaped by innumerable taboos. (Just think of all the things one shouldn’t say about members of the military.) Certainly, some new taboos are emerging, even as some older ones fade away, but no one with Internet access will find it easy to claim that, in general, our speech is more inhibited than it used to be. Taboos discourage some speech, but the system of taboos is also maintained through speech. If you say the unsayable, you might well be shamed—and that shaming can have consequences—but you will not be arrested. Mostly, what inhibits speech is the fear of being spoken about.
