2. It's difficult to even follow the illogic being used.

When the confessors are part of the crime, everything breaks down. No doubt, some of those who confessed their heinous acts were doing so to someone who also sexually abused children. The problem was widespread and endemic in that patriarchal closed culture.

Sexually abusing children is illegal, and is a crime punishable by imprisonment.
Abusers who are prosecuted and imprisoned cannot commit that crime while in prison.
Ergo: Exposing and prosecuting offenders reduces the number of children who are abused by reducing opportunities for abuse.
