To whom do you award the right to decide which speech is harmful, or who is the harmful speaker? Or to determine in advance what are the harmful consequences going to be that we know enough about in advance to prevent? To whom would you give this job? To whom are you going to award the task of being the censor? Isn’t a famous old story that the man who has to read all the pornography, in order to decide what’s fit to be passed and what is fit not to be, is the man most likely to become debauched? Did you hear any speaker in the opposition to this motion, eloquent as one of them was, to whom you would delegate the task of deciding for you what you could read? To whom you would give the job of deciding for you — relieve you of the responsibility of hearing what you might have to hear? Do you know anyone? Hands up. Do you know anyone to whom you’d give this job? Does anyone have a nominee?

Christopher Hitchens (1949-2011) English intellectual, polemicist, socio-political critic
