There are a number of reasons that I think it is a good idea. Because people who have been sexually abused are very likely to have their children sexually abused as they don't know the signs.
I have been involved with incest survivors for almost 25 years and was firmly in the camp of no contact with sexual abuser. But then when I saw how such a great proportion of the offspring get sexually abused anyway because of the lack of skills of child protection I thought there has to be a better way.
Once I was a representative for Adult Survivors of Child Abuse (ASCA) and I met an overseas visitor who represented an Incest Survivors group that had just been accredited to the UN. She worked with incest survivors and her ideas of dealing with sexual abusers really challenged my world view.
Parents by watching their own child rapist they learn the behaviours which ripples out to other areas of their lives. There are discussions and learning which mean they are much more likely to pick up on warning behaviours in other situations.
The child can be told age appropriate things like "We don't trust Grandpa, so we don't go anywhere on our own with him."
By diligently practicing these protective behaviours it means the child learns about safe behaviours and more importantly so does the parent.
I personally think this is one sure way to stop the intergenerational nature of child sexual abuse. Because it is a continual learning curve.
And if we shift to there are really bad parts of people and there are really good parts of people. If we can stop seeing sexual abusers as monsters but real people that need help then we stop assisting them by seeing through the prism of being a monster and we start seeing them as people that we need to have in treatment programs and be monitored.
Seeing sexual predators as monsters actually enables them more access to children as no one wants to admit they have a monster in the family.
If we see them as human beings that have one area we really have to monitor them in - then by looking at reality we provide children with safety and we cut off their access to groom the next generation whether it be in our families or next door neighbour, priest, nun, grandmother, grandfather, female/male relatives.
I mean many people don't even know about female sexual predators.
