The fact that pornography plays a role by fueling these evil desires and eventually leads some to act on those desires is just an obvious conclusion. It has nothing to do with trucks other than you are going to find truckers at truck stops. To pretend blaming pornography is like blaming trucks is a disgusting response.
I think that depends of what kind of "pornography" we're talking about.
If we are talking about explicit images of children, then it would be an obvious conclusion.
If we're talking about seeing the latest centerfold in a men's magazine, or reading the newest bodice-ripper from the library, then I'm not sure the obvious result will be the sexual exploitation of children.
Well, since we’re all making up statistics, I’ll aver that 99.99% of Playboy readers do not molest children, and I expect I would be correct on that statistic. Conflating the viewing of men’s magazine centerfolds with child porn/molestation is also disgusting.
Now, if the article’s author had focused on whether consumption of child porn leads to child molestation, perhaps a geniune corelation (and maybe even causation) could be found. But the author had a broader agenda.
