Passed long by Katy (thanks!). For those unfamiliar with Louis Theroux's Weird Weekends, it's a British TV documentary show that provides a glimpse into the lives of people that you'd not normally encounter. I previously posted a segment he did on bodybuilding.
In this episode, Louis and his crew spend some time in what's ostensibly a long-term prison for sex offenders. It's pretty candid, and it features several men, some of whom exhibit substantial denial and rationalization (which are extremely common in this population), and some who fully admit to their preferences and behaviours (and their consequences). Keep in mind that the show is intended as entertainment and doesn't portray an entirely accurate picture.
WARNING: this may act as a trigger for those who have been victims of sexual abuse.
