Pretty much every guy I knew or dated in my late teens or 20's spent at least some time looking at porn. They led normal lives otherwise, including having normal sex lives with their girlfriends. The mild to moderate use of porn didn't impede them in the least. I noticed that most seemed to outgrow their need for porn once they were somewhere in their thirties.
If porn is completely substituting for a man's sex life, then obviously there's a problem. But I would think that this is the rare exception, and not the rule.
As usual, the Mormons are busy making up a problem where there simply isn't one.
So porn causes both INABILITY to have sex and SEXUAL aggression. I am not a psychiatrist or a doctor but I am pretty sure that when something causes 2 completely opposite effects that it cannot be said that the thing caused the effect.
that starts out with some variation of "a study has found...."
Just about anything can be called "a study" these days. So even if "a study" reaches some conclusion that supports my own position on a particular issue, I take it with a grain of salt.
On the few occasions that I've been energetic enough and have had time enough to really dig in to the details one of these thousands of "studies" that are reported every year in the media, I've been quite surprised at how superficial and weakly designed it turned out to be. Some of the worst offenders have been "studies" that support some aspect of Mormonism, such as the benefits of the Word of Wisdom.
I guess it's been already more than a century since public relations masterminds like Edward Bernays realized how useful it can be in shaping public perception to have a number of ostensibly independent think tanks and institutes conduct "studies" at around the same time and reach similar conclusions.
