 What of pornography i.e. material that is offensive because of its extremely violent or degrading content? In this case the offense is more profound: simply knowing that such material exists is enough to deeply offend many people. The difficulty here is that bare knowledge, i.e., being offended by knowing that something exists or is taking place, is not as serious as being offended by something that one does not like and that one cannot escape. If we allow that films should be banned because some people are offended, even when they do not have to view them, consistency demands that we allow the possibility of prohibiting many forms of expression. A lot of people find strong attacks on religion, or t.v. shows by religious fundamentalists deeply offensive. Feinberg argues that even though some forms of pornography are profoundly offensive to many people, they should not be prohibited on these grounds.
