It sounds as if the scene --- with the non-reacting people -- was meant to titillate if not outright gratify.
There has been a whole rash of novels with pedophilic themes in them, to the point where it has become fashionable. It's called 'edgy', 'dark' and other cliches. White Oleander comes to mind, and for my money, Lolita goes inthe same category.
I can't imagine this scene being other than gratiuitous and aimged at pedophiles.
when a scene and characters don't make sense and seem highly improbable, when there are no consequences of such an act you're dealing with pornography.
Where are the consequences? Does the narrative follow the brutalized child and describe his/her terror, feeling of violation?
No? Porn fantasy.
Hah. Don't make a fool of yourself. Have you read Lolita?
Lolita isn’t pornographic. It doesn’t contain any descriptions of sex.
