Years ago on this site, when (passing) trans people were still called "traps"—maybe around 2011 before trans identification skyrocketed—some tripcodefag who loved crossdressing and posting his "programming socks" explained his reasoning. He said that after years of dedicating his whole self to anime, he slowly went from "I want to love the little girl" to "I want to BE the little girl", the taboo feeling of crossdressing aroused him. He also mentioned how he enjoyed confusing people about their sexuality when talking in private.
Multiply a whole bunch of retards like this and exponentiate it throughout over a decade of actual grooming—and on top of that—have a bunch of normie/externals repeating to them "you don't have a weird fetish, you actually are a real woman! :)". That's what caused it.
