I'd respectfully argue this one as being finicky and highly situational depending on the context, especially with fiction. I'm not for "you can't read about x mature thing", but this is one of those areas where source and context matters WAY more than subject matter and I wish more parents (and teenagers, kids are gonna think it sucks regardless) would think that way. One of the few areas I'll helicopter to some degree because I'm young enough to remember being that kid.
If they're learning from and exploring the wrong sources with no outside input it's going to do damage. Not necessarily trauma, but it can push their views on those topics in uncomfortable directions if left unchecked. (Note: I say can. Not does.) It's a "taking the teacher at their word" moment, only the teacher is a young 20-something writing fanfiction on the internet and not properly tagging their shit.
(Pre-submit warning: Anecdote/tangent follows.)
Coming at this from the parent direction: I just screened a YA novel for Cat that, 300 pages in, veered suddenly into a 2-page almost-but-not-quite-went-all-the-way-because-it-was-interrupted SA between the protagonist and her father. (Admittedly I would have known about that scene had I read actual reviews rather than official blurbs, which omitted that particular warning for some reason.)
I finished reading it quite literally yesterday. It's not a loan; She bought this book. She'd started it before me. We are/were a "you will never be grounded from reading or have your books taken away for any reason" household. Making this decision to not give it back to her (yet) is weirdly one of the most conflicted parenting decisions I've made in her life so far, especially since the scene doesn't get explicit.
I know at my kid's age, I would have read those pages out of curiosity even if they did "go there". They wouldn't have been upsetting, I was a tough-ass kid when it came to darker topics and reading. But I also know that at her age, I would not (and could not!) have had the experience I do now to see just how disrespectful and downright BAD the portrayal was in that YA novel. The kind of scene that is tossed in to spur emotional outrage or fear in the reader rather than contribute to the book in any meaningful way. Used as a tool for rage-bait.
I love her, and she is incredibly intelligent for her age, but she is also an information sponge. Many youth are, even if some adults want to pretend they're not paying attention. Being an information sponge with inexperienced exposure to not-so-great source material is... Not good. (Hell, look at how easily grown adults fall into that trap.)
That, as a parent trying to raise a good human, fucking terrifies me.
Adult me reads that scene, and admittedly? I feel like I'm Karen-ing on this. I'm angry about it. Offended, even. Again, not about the subject matter, but that my kid might have been exposed to it so casually, as nothing more than rage-bait that gets brushed aside the second it's not directly convenient to the plot. If I hadn't screened it, I worry that she might have assumed/taken some things in that book to heart that really should not be normalized.
Do I think kids need to be sheltered from concepts as a whole? Oh holy mother of fuck no, because that's how you get kids who feel lost in their own home, or don't speak up about abuse. But I do know that if (and when) my kid is exposed to this kind of thing in literature, fiction or no, that it should be from a source that handles the subject matter with at least some illusion of tact. That, I can help her with. I can at least try.
So I'm more saying "please don't read about that topic until I can look it over first or we can talk together" rather than banning it entirely.
Shit... Never ban information; Educate on where and how to use it properly.
Bleh. Tangent. Veering way off topic.
I swear I'm not arguing against the post. I think I was going somewhere with this, more as a defense of parents who *do* take issue with/take away stuff like that for the right reasons.
"Defense of a middleground," if that makes sense.
