Some Utilitarians conclude that pornography is wrong
based on five harmful consequences it has on society:


1.) Pornography reduces the dignity of human life.
2.) Creates an environment where true victims of sexual
abuse are less likely to be dealt with sympathetically by the
justice system.
3.) People imitate crimes that they have seen portrayed in
pornography.
4.) Offends most people.
5.) Existence of the pornography industry diverts resources
from activities that would have more redeeming social value.
