I'm curious of your take on one thing. Many of the sexuality oriented books (which your list is overwhelmingly composed of) tend to, unsurprisingly, have sexual content which is often rather explicit. Some of these books even have explicit artwork within them. I'm sure you'd agree that if books had ratings then many/all of these books would R, if not NC17, rated.
And even in high schools screening R-rated movies is generally heavily restricted. Where it is allowed, it generally requires a permission slip from the parents. And that's not like showing gratuitous films, but ones with historically relevant and educational context like e.g. Schindler's List.
So why is it unreasonable for parents (or other interested parties) to be against having such material in a children's library? In many ways its quite odd that a rating system was never adopted for books. And for one other question, do you even see a difference between these sort of books being restricted from schools, and other books whose content would be generally be rated appropriate for children, being banned on political/ideological basis? Because to me the difference is not only tremendous but the defining issue here.
