No as it's almost impossible to attribute these effect to porn as porn is too widely spread among women and men, and most of the "porn behavior" existed before that porn was universally consumed. Strangely most of these studies talked about men behavior when women consume a lot of porn.
This is the same kind of things you hear about gay, role playing games, metal music, video games, rap music that are all rotting the brain of young people.
I understand the censorship argument also, and to be honest expecting also people defending their right to watch porn, the addiction is real.
Porn is like a thought virus, if you watch it enough you will start to think about all these things you see visually about the women in your life and people around you. Many people might not want to admit this, and will just spew out silly comments defending porn, maybe they are addicted to it and like to watch it.
Then go ahead, I'm not saying you should not be able to watch porn.
I'm saying _by default_, things like porn should be more harder to find and access.
