THAT'S OBSCENE
From a review of Whitney Strub's Obscenity Rules: Roth v. United States and the Long Struggle over Sexual Expression in the Wall Street Journal:
It shouldn't be surprising that progressives have certain visions of a good society and are willing to suppress speech in pursuing them. Such liberal objectives aren't different in kind from the desire to maintain a culture with limits on the expression of sexual vulgarity, a desire once expressed on both the left and right. Neither objective is anti-intellectual; both involve large aspirations that aren't reducible to arguments about short-term empirical evidence. Mr. Strub's simplistic left-right frame notwithstanding, "Obscenity Rules" shows that both liberals and conservatives are often willing to subordinate freedom of speech in their quest for what they believe to be a decent moral order.
