A better source that points out the same thing:
inappropriate contentography: Beneficial or Detrimental?
I could go on. There have been no real drawbacks to inappropriate content. "inappropriate content addiction" is mostly nonsense. There may be a few people out there that can't control themselves, but one has to wonder what they would to to relieve themselves if inappropriate content was not available. They could be the people that do not rape when inappropriate content is available.
If people do not like inappropriate content, they can simply avoid it. Forcing someone to watch or see it that did not want to would be wrong too of course. So if you don't want to see it, don't watch it. And you do not have to feel guilty for not wanting to watch it, nor should others hassle you for that. Of course turnabout is fair play. You should not hassle your friends, coworkers, and neighbors that like inappropriate content.
