To answer better about why you go to Toddlers and Tiaras and pedophilia all the time. Scientists have done studies where they watch what part of the brain lights up when discussing topics. They found that some memories show up in a part of the brain for cognitive thinking and emotions all at once. Events that are very traumatic have strong links in the emotional centers, and when other events trigger the same emotions, it brings back old memories that were tied to that emotion. It kind of explains PTSD. Let’s say someone survives a battle, and during the battle they were terrified and had horrible feelings of despair and lack of control. Then after the fact, months or years later, they are having a conversation about something unrelated that triggers these same emotions. The brain, once one of the emotions related to the first event is triggered, regains all those horrible feelings in that moment, even can bring back images from the first event. Kind of the reverse of the original event where a horrible thing happened and then you react emotionally to the event, this time the emotion is tapped, and it brings back the memories of events that have tapped that emotion before. So, the person is re-living the feelings with just as much intensity, even picturing the event vividly sometimes.
And, unrelated, I agree with @zenvelo also.
