The reality is that the elementary school is... Not likely to have 50 shades of gray in the school library.

It is not unreasonable to have a policy about books that are appropriate and a policy about how to handle complaints, but at the same time those policies will be abused. I don't think there is a great way to deal with clashes like this so would tend to veer on the side of being more permissive rather than allowing more restrictions.

The framework would allow some towns to do things like banning cute books about penguins that are entirely age appropriate.

A lot of things working correctly are based on the notion of everyone involved acting in good faith, and when people do not, it wrecks the systems that might be set up. Most parents know that their children are exposed to things in public that they are not exposed to at home. Hiding a few books from them is not going to change the influences on their kids.

As soon as parents go in a direction that is basically "I don't want my kid exposed to this because it is against my religion" it reminds me of why we have separation of church and state. That's nice. Many books feature stories that clash with many religions. Do we go through all the books and make sure that everything would be appropriate for a strict adherent to Jainism too? Now that is truly "woke"...

Except that it isn't.

I can only hope that the people of this fine state can live and let live, but a significant proportion of the population wishes to have a culture war - and ironically those people are the ones that claim the mantle of freedom.
