> Maybe, but at the same time there is a serious issue with adult/sexual content in fictional books with no real historical or scientific value.

Is there? Because I've heard this and everytime it's been an hallucination.

And also text on a page is not sexual. Its true that literary classics like "Kite Runner" include rape. But that's not a sexual book.

Is there actual, literal smut on school library shelves? Almost certainly not.

Its not a problem of sexual content, but rather a cultural problem of extreme prudism and purity culture, coupled with religious extremism.
