In some cases there seems to be real introspection, others not so much. That said, it was bold of Reddit to host this thread and if reading it helps others cope with their own histories, I'll be thankful.
IMHO the more interesting tales on that thread are from people who talk about relatives and friends who have raped. Knowing rapists who have been convicted and still not taking responsibility for their actions is incredibly frustrating but more so when the perpetrator's a child molester and his family acts as if there's no need to worry about that person being around other children.
The worst rapist/child molester that I've known raped more at least a half dozen women and repeatedly molested at least five girls in his own family. He was never charged because the adult women excused his behavior because he was drunk and the girls were all family members in what we later learned was a multi-generational family of sexual abusers. The head of the family was also a pillar of the community. AFAIK no one in this family has ever been brought up on charges. I know that two of the girls confronted him as a young adults. All that it got them was shunning by the family and badmouthing in the community.
