Genuinely, one of the measures that's stopped book banning the most when districts implement it, is having the would-be banners fill out a form that demonstrates if they've read the book or not. Like where they have the summarize the plot and characters and do a mini book report and give a review. It stops them in their tracks. This is why in my high school, every time someone wanted to ban a book it ended up going nowhere. There was one where a conservative student wanted to ban the manga "Legal Drug" for having a marijuana leaf on the cover, then got the form that required them to actually read and either balked, or read it and realized it was not pro-drug at all. (The other one that reduces book bans even further is "requiring the would-be banner to be affiliated with this actual school in some way, either by being a student, faculty/staff or a parent of a child at the school" because the vast majority of bans are "activists" with no affiliation with the school who just travel around trying to do this in districts all over the U.S. IIRC a few years ago someone crunched the numbers and just 51 parents were responsible for all the book bans that year nationally. 51! In a country with 50 states, with over 300 million people total!)
Laws like this indeed do a lot to stop fascist book censorship. They can also help legally protect librarians from getting fired or harassed for keeping books on the shelves! Some states like Rhode Island have already passed these laws. If you're in a blue state, look up whether you have laws like this on the books. MAYBE your state is trying to get one passed right now, like New York's Freedom to Read bill. call your state elected officials to voice support for it.
