This topic is unusual for eNotes, which can make it difficult to be specific in discussion. Pornography harms in many ways. First of all, it harms the youth because of people looking for child pornography and reinforces the twisted attitude of the viewer toward children. Pornography hurts normal relationships by distorting what someone might put into a marriage relationship because of spending time looking at pornography instead. The person so fascinated with pornography learns to be secretive with everyone, which also destroys chances of intimacy in a marriage. If they are young adults, they learn to look at women or children or men as objects, not people, and to believe that what can be done to them is acceptable, even pleasurable. The people in the pictures or films of pornography are very often not there by choice--it might even be true to say seldom there by choice--and learn to feel hopeless and worthless.
Speaking as a person who goes into jails as a crisis counselor, I have dealt with those who see pornography as a victimless crime, which it is not. I also go to a homeless shelter for youths 16-24, and the victims of pornography there are often feeling suicidal about being involved in the industry, even though such involvement may be the only way they can see out of their homeless dilemma. Pornography is not a victimless crime; I see it as one of the true evils of the world fed by child trafficking and prostitution. I hope this answer helps you in your paper.
