 What about the claim that pornography violates women’s right to freedom of speech? The argument rests on a “dangerous confusion,” Dworkin thinks: the confusion of positive and negative liberty. It rests on the “unacceptable proposition: that the right to free speech includes a right to circumstances that encourage one to speak, and a right that others grasp and respect what one means to say….These are obviously not rights that any society can recognise or enforce. Creationists, flat-earthers, and bigots, for example, are ridiculed in many parts of America now; that ridicule undoubtedly dampens the enthusiasm that many of them have for speaking out and limits the attention others pay to what they have to say” (Dworkin 1993, 38). But, Dworkin suggests, we surely should not think that this violates their right to freedom of speech: e.g., that creationists have a legitimate claim on the state to ban the publication of books or videos recommending the theory of evolution on the grounds that these may cause the speech of creationists to receive an unsympathetic or dismissive reception.
