Is there a DSM-IV category for it?
Interesting question. I am beginning to believe there really is some confluence of psychological pathologies that lead to this condition. This is not a scientific analysis, but frequently I have found the most virulent anti-Palinites seem unalterably fixated on her female attractiveness. They invert it in a sense to use it as a weapon against her supporters, but it is there nonetheless, somehow operating to transform her every deed into relational terms of gender attraction, like "jilted" or "worshipped," etc., almost as if the bitter poster is reliving some failed relationship in their own past. It would be a fascinating thing to study at a clinical level.
Yeah, I am sure all those cainites felt jilted. They are just as bad.
