What is the proper role of pornography in American society?

I think porn plays a bad role in American society because so many people are involved with it and get so obsessed with it. It takes up so much time in peoples lives and does them no good. Whether they're sitting at home watching it on their tv or watching it on the internet; it's everywhere! Porn can become a bad habit to anyone like the man we saw who lost everything because he was so obsessed and involved with porn. People say porn is their "escape" or helps them have their own time, but that's where the addiction starts. It also makes people think that they need to be like the girls or the guys being filmed, or even act as they do. Also, it puts a sterotype on housewives, school girls, and others.
