Sue loves attacking WWASPS because, somewhere in that addled brain of hers, she thinks that as long as she gets some kids out of one abusive system, it's perfectly okay to make money putting kids into different ones.
That's all there is to it.
She foolishly shows up trying to plump for CAICA/PURE every onece in a while, and we on Fornits don't have any patience for that kind of repeated misdirection, which is why the subject comes up again and again.
