In regards to blaming the victims:  If humanity were as smart as those of you "who get it" then we wouldn't have needed Jesus Christ to overcome the devil.  Look, even Mr. & Mrs. Pfeiffer have "allowed" themselves to be fooled.  Maybe we weren't exactly fooled, as you think.  Maybe we just keep overlooking these abuses and offering them up.  We turn the other cheek  - for a while.  I am sure Mr. & Mrs Pfeiffer's offering of their property was poured out to our Lord as a sacrifice.  We are admonished to give our 2nd coat, to not ask the return of a borrowed item, to give, give, give.  We aren't as foolish as you think.  We are just givers, and we do it in the Name of Christ.  Just because I have now decided to expose the situation doesn't mean I was so foolish in making sacrifices and turning the other cheek.  It just means that there is enough trouble there for a major intervention and that assistance is needed. I hoped and prayed that my sacrifices would be used to straighten this mess up and move us forward to the Reign of Mary.  I am sure Mr. & Mrs Pfeiffer are hoping a praying for their lost son, Fr. Pfeiffer.  
As I said earlier, this is the same situation as loving someone and then being betrayed by that person -- whether by abuse, infidelity, etc.
Was it the victim's fault for trusting and loving? Of course not. Without love and trust, life isn't worth living. 
I do believe Catholics are easy targets, since they are charitable, they think the best of others, and they are innocent. "To the clean, all things are clean." For an honest person, it's hard to believe someone would lie to you. To a just man, it's hard to believe someone would actually cheat or steal from you. For a chaste woman, it's hard to imagine a man would be unchaste.
How many young boys have trusted their priests, and later got abused and betrayed by them? But you certainly can't blame the boys -- priests are supposed to be holy ministers of God!
It works in reverse too: a liar has a hard time believing others. And an immoral (unchaste) person has a hard time believing anyone else can be chaste. And a thief suspects everyone is trying to steal from him.
Shame on the man/woman who takes advantage of a person, and betrays that love and trust! But there is no shame in loving, which inherently makes us vulnerable.
