Even if my sister had a girl friend or business associate that was in such danger she would call me and I'd take care of it. These situations have more to them than is said. Likely the girl was a total loner with no friends whatsoever.

I didn't watch the video in which Miss Kauffman gives her testimony, so there are a few things that aren't clear. There seem to be a few glaring omissions in Michael Matt's analysis, so I have a few questions. Michael Matt goes on and on about this and that in his article, but he doesn't address some basic questions:

Did Miss Kauffman tell anyone in the SSPX about her situation and accusations back when it happened, or since, until now? I don't see any mention of this by Michael Matt.

When did the SSPX first learn of Miss Kauffman's accusations? Has there been any investigation by the SSPX of said priest? Have they even heard of Miss Kauffman's accusations? I would hope so, but that isn't made clear.

What sort of justice is Miss Kauffman hoping to achieve, exactly? The article says that......"I will allow Miss Kauffman to bring her case to the attention of our readers for the purpose of achieving justice for her as well as preventing further scandal."

I'm not on any one side in this - I just think that since Michael Matt is posting this situation in a public manner, he should provide more basic info, which doesn't require watching a video.

I asked her for corroborating evidence, i.e., a birth certificate for her child (now adopted) or some other notarized docuмent that establishes paternity. This Miss Kauffman made available to me, along with other corroborating docuмents.  [/font][/size]

I must admit, I always have a problem with these types of stories for this reason.  Even the first time, it seems like so often the person didn't fight as hard as they could.  I would run away, or kick, punch, scratch, scream, and do whatever I could to ward off a rape. He'd have to beat me black & blue.  And I especially never understand the repeated cases.  If someone did this to me once, I would do as the posts above suggest: seek help from friends, ask landlord to change locks, or if my landlord was too cheap to do it, I'd change the locks myself.  If I didn't have the money for the locks, I'd find someone to loan me the money. I'd place a piece of heavy furniture in front of the door if I had to. I'd have some pepper spray handy, and if he tried again, spray him & call the police.  ANYTHING to prevent it happening again.  Maybe the woman in this story did some of this, but it doesn't sound like it from some of the comments here, and in other alleged cases of priest-abuse, it seems like the victim is always available for further abuse.  I don't understand it.

Fr. Arzuaga was not a big/strong man and he was by her account heavily intoxicated.  Had she physically resisted, I don’t see how she couldn’t have thwarted any attempted rape on his part.  And the fact that this happened over and over again without her having done much of anything to prevent it ... I agree that it doesn’t pass a smell test.  It’s also interesting that she won’t name this confessor who could theoretically back up parts of her story.  So she would just lay there every night wondering if Fr. Arzuaga would show up to rape her?  “I’m glad he didn’t show up tonight to rape me.”  Wouldn’t you just move or do SOMEthing?  Then she plays the “shaming” card ... asserting that anyone who doesn’t accept everything she says to be true is shaming her.  That’s garbage.

Last Tradhican had asked: To anyone that watches it clear through, it would be great if they would post here the details of what she said. Thanks and God Bless.)  

If it were me, and the story were true, I would want other young girls to be aware this happened to protect themselves. Young girls tend to believe that their priests can do no wrong and their guard goes down around them when, in other circuмstances, they would be wary of a man.
So to answer the why: perhaps to possibly help for this to not happen to another girl. Someone else's daughter and sister. Some other family that would go through hell.
