And, I also downvoted this comment because asking why you're being downvoted is not only dull, it adds nothing to the conversation.
If you would read my reply again, you'll note that I said, "I downvoted you because of the suggestion that "most books" are appropriate for (and interesting to) 8-14 year old girls."
Frankly, I don't think that's controversial enough to have to explain.
First, it's flat out wrong to group 8-14 year old girls together. The sheer amount that girls grow between those years makes that highly questionable. The kind of book that the average 8 year old would gain from would be insulting to the average 14 year old. And the kind of book that a 14 year old girl would gain from wouldn't make much sense to the average 8 year old.
And yes, there are outliers, but if your child is an outlier, for the love of all that is holy, spend time in bookstores with her and figure out what she's actually interested in. In distributions like this, outliers tend to have very strong interests that overwhelm all the social pressure. If you're dealing with an outlier, figure out those interests and cater to them.
Second, let's look at the word "most". Do we have to talk about how most popular fiction geared towards adults may not be appropriate for the average 8 year old? And what about interest? I'm a 40 year old man who reads voraciously yet "most" books are neither appropriate, nor interesting to me. There isn't anything wrong with that. It's just that we all have interests.
It's annoying when someone edits a comment to ask why they were downvoted. But, it's flat out dull when they edit a comment and then make an entirely different reply to ask the same thing. That adds absolutely nothing to the conversation.
To answer it succinctly, I'll use the programming language example that I used.
Let's say that you have never programmed before, so you come to me for help. I start teaching you. The first lesson, I teach you how to output "hello world". The second lesson, I teach you about monads. Honestly, how do you think you'd do?
There isn't anything absolutely wrong about monads, but I'd tend to argue that they're a little too advanced for someone who only knows how to output "hello world". In this example, I'd say that teaching you about monads in the second lesson was inappropriate - you likely won't gain from it, in fact, it's more likely that learning about monads too soon will actually hurt your progress.
There. Just a friendly suggestion: I think you may be a bit over-extrapolating from your personal experience and your sense of "common sense", to make overgeneralized statements about things as arguably complex and idiosyncratic as "appropriateness" or "interest" in books. (Hence, perhaps, the pushback from other readers.)
Young girls are primary demographic for reading. While it is true that 8 years old are not there, 14 years old already are. Majority of what is in bookstore is appropriate, maybe boring, but I don't recall running into something super inappropriate while randomly browsing bookstore.
Second, I don't think that 8 year old girls and 14 year old girls should be grouped together. I have an 8 year old stepdaughter and she talks to her stuffed animals. She knows (at least, I hope she knows) that Unicorn is stuffed and I make her voice. But, she still talks to, argues with and consoles Unicorn. And, when I meet her friends, she wants her friends to meet Unicorn.
Let's flash forward six years. What do you think she will say/do if I talk like Unicorn in front of her friends? Or, what will happen if her first boyfriend comes over for dinner, I plop a faded old stuffed unicorn on the dinner table, affect a squeaky voice and ask him "do you like unicorns?" That's not appropriate! It will either embarrass her, keep her friends away from me, or otherwise hurt my relationship with her.
Finally, you talked about how you don't recall running into something super inappropriate while browsing bookstores. I'm not talking about Fifty Shades type of stuff. Rather, let me give you an example.
I love The Catcher in The Rye and genuinely believe that every person should be required to read it before being allowed to graduate from high school.
So, that's a book that I would definitely recommend to 12-16 year olds. The thing about the Catcher is that it's best when you've already started questioning the social world around you. Otherwise, it's too easy to declare Holden Caulfield a whiny little twat and not gain from the book.
So, I would argue that while that book is amazing and all kids deserve a copy, not every kid will be ready for it at the same age. So, while the sentiment is appropriate, the book isn't appropriate for every young person at the same time.
Or, in terms of code, let's say that you've never programmed before. It wouldn't be appropriate to teach you "hello world" then go right into monads. There's nothing particularly wrong with monads, it's just that they would be so far beyond you that you wouldn't gain from the lesson.
2.) I did not objected to your downvote further. I was honestly curious when I asked those questions. (And also appreciated the answer about glib interpretation.)
For the rest, thank you for answer. I guess I have every different opinion about amount of harmful books for kids in bookstores or maybe we have different bookstores around here. At that age, I was freely selecting books from adult section in local library without any supervision or control. I assumed that other girl is the same.
