Again, the policies are not the problem. It's deciding what falls under the policy, and where the "boundary of appropriateness" is.
One website blocked here in Katy ISD is The Trevor Project, which is a suicide prevention support site for LGBTQ youth.
I strongly encourage you to visit this site for 2 minutes and imagine having to explain what policy this site violates.

This is a small group of busybodies trying to declare that their "boundary of appropriateness" should apply to all students. That's just a pleasant form of thoughtcrime.
A simple solution would be a third category between "appropriate" and "inappropriate " - call it "borderline" - and have an opt in policy for children for these books.
Letting each parent decide for their own child what is appropriate is fine.
What's happening here is not.
