>>2556023ey, sorry, I didn't see you there.
Maybe the trauma could come from how /pol/ raised her. After the death of /mlpol/ he'd have wanted to turn /bant/anna into /mlpol/ 2.0, and with his increasingly cultish mindset as a result of Kek worship and reddit influence, he would have tried to indoctrinate her. Then she would have some sorts of experiences with others that would cause her to question or even reject some of the teachings of her father and reddit. (This would also give further explanation to her frog hate) /pol/ reacts harshly to this, trying to isolate her and cut her off from "jewish" influence. She escapes and eventually gets accepted into 4chan proper, where /pol/ doesn't have too much control over her anymore, but still tries to get her to accept his views by shoving imptrash her way.
What would make this dynamic interesting, in my opinion, is that it would show that /pol/-tan really cares for his daughter, but because of his cultish mindset everything he tried to teach her backfired and caused her to hate him, with good reason.
(I also had a side idea where /pol/ is bribing hiroyuki to let him stay in 4chan despite all the trouble he causes by getting his reddit friends to watch and click on all the ads. I think there's some potential for it)
