There are no statistics to compare religious to non religious in that link.
"No less likely"
You believe that the incidents of abuse are similar in frequency between religious and non religious educational institutions?
Yes, I believe the incidents of abuse are similar in frequency, if not more common in places where kids are told that the adults minding them are their moral and spiritual superiors to be trusted above all else.
Back to the topic of the "Christian" boys camp, I have absolutely no problem with people opting for that route. It's your kids, send them where you want. But they are no more safe than any other just because they don't allow (openly) gay men and boys into the club. It's naive to think they are and it's that kind of naivety that causes parents to brush off their kids' accusations. "Impossible Jimmy, that's Reverend Fondlesalot. He would never do something like that. He's a godly man!"
In medical fields there's an old joke that each discipline tends to draw it's own abusers. Pill heads become pharmacists, crazies become psychologists, hypochondriacs become immunologists and so on.
There is some of this in religion, I think. Christianity in particular has a byzantine and regressive stance on human sexuality and deviance, in addition to a strong emphasis on guilt (being "born sick", in other words, and commanded to be well). As a result I think it's professionals -- priests and preachers -- are probably made up of a higher percentage than the average of sexual and moral deviants.
I think it was Freud who said we hate what we secretly desire. I've always thought it was closer to the truth to say that we hate what we secretly fear becoming. In either case it's close the same basic idea.
It's absolutely amazing how quickly the American populace has turned around on this issue.
