No, I won't bother reading them all. There is an infinite amount of spin out there; rather than sort through it all I'll just rely on the APA.

I did follow one link, however. It suggested that Porn use predicted violent sexual behavior. Here is the actual link:

http://onlinelibrary.wiley.com/doi/10.1002/ab.20172/abstract

"Abstract: Further analyses revealed that the predictive utility of pornography was due to its discriminative ability only among men classified (based on their other risk characteristics) at relatively high risk for sexual aggression."

The abstract itself says its findings apply only to men predisposed to sexual aggression, and could not be generalized to the population at large. This suggests that your researcher is either sloppy or misrepresenting the research.

So I figured it might be worth finding some surveys or metastudies. Here is a shotgun of them:

"Conclusions: The paper suggests that consuming pornography is not a significant factor in the generation of negative attitudes towards women." http://www.tandfonline.com/doi/abs/10.1300/J514v19n01_05?src=recsys

"Review of the literature shows that sex offenders typically do not have earlier or more unusual exposure to pornography in childhood or adolescence, compared to nonoffenders." http://www.tandfonline.com/doi/abs/10.1207/s15324834basp1804_4

"Men who are not predisposed are unlikely to show an effect; if there actually is an effect, it is likely to be transient because these men would not normally seek violent pornography." http://www.sciencedirect.com/science/article/pii/S1359178999000075

"The summary demonstrates a homogeneous set of results showing that pictorial nudity reduces subsequent aggressive behavior." http://onlinelibrary.wiley.com/doi/10.1111/j.1468-2958.1995.tb00368.x/abstract

The research seems pretty clear to me. Porn is, at best, a side issue. Its not the crisis the church wants it to be.
