No, because restricting expression inhibits freedom of thought, reflects hostility to sexuality, and requires subjective, dubious judgments. Filters may be improving with technology, but in the past they have censored health information, literature, politics, and other domains of expression that ought to be sacrosanct, even by the standards of most anti-pornography proponents of such laws. The subjectivity on rampant display here, however, is not restricted to the vagaries of technology. Who is authorized to judge what counts as profane and what degree and manner of reference to the basic human topic of sexuality is excessive? More and more speech can easily come to be seen as dangerous once a fearful mindset takes hold among lawmakers, activists, and the public. This line of thought is an invitation to unchecked paranoia. It's surely wiser to teach ourselves and our children the value of health education and media literacy, including skepticism, consciously filtering the material one encounters, discussing it openly, and cultivating humor, curiosity, toughness, and tolerance.
