I too think Duggar is getting the short end of the stick. He was a stupid teenager and did stupid teenage shit.
Cosby and Jarod, those two are a different plane all together. Duggar is more like family gossip of the stupid teen kind... Jarod and Cosby - they engaged in this nonsense victimizing people who have no idea what they were getting into (IMO). Jarod and Cosby had fully developed brains and were at least aware of moral systems - where Duggar's wasn't.
Cosby, ya drank something and ended up waking with your pants around your ankles and him with a for shit grin. I am concerned about how that is being overlooked because it means it is your fault for accepting a drink as a guest and turning into a Cosby masturbation toy. It's like some greek myth or something.
Jarod, well, I think it is just obvious. Hey little girl, want some candy? That girl has no idea what she is getting into. The teenage girl has more of an idea, and is willing to trade it for some dollars - but I doubt it was all the way thought out. And to brag about it too? More sad than a PL saying "How she wanted me" after spending three digits on her.
