A while back I decided to fact check the claim that porn is dangerous; because I felt like it.
What I found is that most of studies that "support" this claim are pretty bad.
- The samples are biased towards a normative result.
- Sample size is too small.
- The study takes a biased stance (usually stating an arbitrary result).
Wikipedia mentions this issue.
Further more I never received permanent harm from porn; in fact I didn't even receive harm at all.
In my experience, all of my "addiction" issues with porn are just ADHD behaviors that would have applied to other entertainment anyway.
I emphasized that porn is not dangerous to the viewer; porn can be harmful to the actors if safety is not properly maintained; but this statement can be said for every type of entertainment that is not complete animation.
