But pretty much all of these book bans working their way through schools absolutely DO infringe freedom of expression. As is the goal.
I see no problem with using these badly-written bans to hoist these people by their own petards until they stop spreading their evil into schools in the name of a religion. Because the Bible contains all the necessary themes to get it "legitimately" banned under any of these laws, proving clearly how overly broad and arbitrary the laws are.
