If you look at her history and the sites she used on the internet growing up, it kind of makes sense. She was on tumblr while it was a hellhole and started to believe some of the stuff they pushed which she herself admitted, while also being on 4chan and probably was also a fan of Jim at the time and god knows what else she was looking at and all that. She probably got a shit ton of conflicting shit pushed on her and knowing Pippa she probably just absorbed it all.
