The former I agree has the reaction of the Streisand effect (like Dr Seuss-gate)
However if a kid can get the book from online store with relative ease, or lookup why it’s banned and find it’s benign, I don’t think it’ll have nearly the effect this article predicts.
In a school setting, I’m not against the library within the school being more restricted - it should be on the parents to provide, or withhold, books from kids when they deem appropriate.
And if a board elects to have a book removed, then the process worked. Let the PTA or others voice concerns, or better yet, just get the book for your kid.
I’d rather have the school library too strict than too relaxed with selection.
Let the parents parent. If they want to take their kid to a public library, or get the books themselves, let that happen. This isn’t some mass societal book burning
