Keep in mind that Chris spent a long time interacting with people who fed into his delusions and there's every possibility that Chris was manipulated into talking about something that didn't actually happen.
Barb was examined for rape and it doesn't seem like that came back positive. At Barb's age, even consensual sex would cause tears and damage that would be identifiable.
Chris was arrested for violating his no-contact order when he stole $700 (I think) from Barb's account. Not for the incest charges. He was released after that happened and used the money to get a motel room (where he was arrested) after his relatives wouldn't let him stay with them following being removed from Barb's house.
The point being. There's no point in condemning Chris when anything he says could have taken place in his CPU Goddess CWCville universe and not in reality. I personally believe he invented the story due to manipulation by Sean, ILJ, and others involved in that situation.
No one knows what happened before the call started being recorded, no one knows how long the real call was. No one knows what was said that precipitated the incest leak. I believe the truth is somewhere in the middle. So don't condemn Chris too much considering all that.
Only Chris, Barb and God know what happened for sure, and 2/3 are unreliable narrators.
I bet if you picked a lolcow out in the wild you could write a funny thread on them.
