I think it is good to review the statistics. The ones about abuse in the home. About the outcomes of porn for those who are involved in it, and what it does to women in general (and males etc who are trapped by the trade.)
I don't see any problem with the information being on a Christian site, since they didn't make the problem up, it's real. A lot of secular sites won't tell the whole truth. I wouldn't want to invite it into my home, nor would I allow it to stay if it arrived. It's not a good thing at all, whether you're a Christian or not, to have these problems in your household and relationships. It overtakes the viewer. However, if someone returns here with how their guy is addicted to porn, in the future, they'd still receive support on how to work through it, or get a divorce.
Here's another link, about a study (2002)

Oh and I disagree with the idea that the "majority" of guys out there look at porn. That just isn't so. It's not normal behavior for constant use of such.
