Parents NEED to lodge formal complaints with the police and school boards in EVERY district that still has dictionaries and encyclopedias in the libraries.
Whittle down every district until they're only allowed to work on coloring books for every grade K-12, or as close as they can get.
Don't forget to target private schools with massive social media campaigns to inform all parents that dictionaries = grooming. If the private schools refuse to respond, convince the dumber wealthy parents to pull their kids and put them into a safe school, without books.
