I would add as well that most of the well-documented negative effects of pornography are also found to be caused by other forms of sexualized media that aren't explicit. For most of the things that we see in youth that we are fairly confident are caused or influenced by pornography are also caused by sexualized advertising, sexualized music videos, and so on. In some ways, pornography really is just the most extreme end, but blocking that is only going to have a very limited effect on those issues. We really need to take a broader media literacy look at gender and sexuality and those related issues to be effective.
