You can blame everything and anything on porn. Same thing with rap music, religion, guns, social media, recreational drugs, etc.
Anything you do that exceeds the normal average is addicting so for people to say porn is addicting.. yeah well same can be said about video games, eating, drinking, etc. It's not the subject per say that is addicting, it's the person's overall behavior. Just like the saying of how if you smoke pot, it's a gateway drug, and you will end up doing heroin.
Yes certain videos are very bad such as a young girl getting blasted by 20 dudes but the majority of viewers aren't watching those types of videos. Young people use porn as basic sex education which is a good thing. Porn provides the skills that will ultimately lead to a much more satisfying sex life, whether alone or with a partner.
Just look at the middle east as an example of the violence against woman. Porn is basically unlawful there and rape/crimes against woman is still going on. Hell there are probably more rape and violence against woman in these 3rd world countries that lack porn.
