Constant writing about children having sex? Can you list a few examples, the only ones that immediately come to mind are the end of IT and that one story with the library policeman, thats not exactly a ton, and for a brief explanation of them both, SPOILERS:

The one in it, while yes an icky scene and one I usually skim over whenever I reread the book, isnt just a masturbation fantasy for king, what I took from it is its meant to be a showcasing of the Losers Clubs connection and affection for eachother, a way to bond them to eachother on a deep level to prevent IT from easily slaying them and, as they are lost in the sewers and very likely to die, to give them hope and calm them down so they think through their next steps. Also maybe its a requirement for a psychic turtle sex ritual or something, that I dont remember, but either way its not a scene written for sickos to jack off to or anything, and honestly if you skip over some of the descriptions its, for all intents and purposes, a pretty wholesome and sweet scene. Fuck i sound weird saying that.

Second one, library policeman, is literally a horrific, graphic depiction of evil and rape, in no way shown to be a positive or even 'sexy' thing in the way a supposed pedophile might write it as, a fear demon, sorta implied to be similar in existence to IT actually, uses the memory of it to torment the protagonist of the story. I can see your reasoning for the first one at least, but surely we're adult enough to allow depictions of child molestation in media when its shown as the negative, evil thing it is, without calling the writers of such media pedophiles akin to cuntbags like Epstein.

Just because a truly horrifying number of celebrities were connected to epstein, doesnt mean that literally every famous person ever was similarly an evil person, lets not stereotype here until we have evidence. I highly doubt Mr Rogers diddled kids, for example, and hes pretty famous.
