The only thing is that there's not really a vehicle for the fed to implement those bans. For all the weaknesses in the US constitution, freedom of speech is a historically tough nut for the government to crack. Not that they haven't tried, but they have almost no control over what media is and is not allowed to be published publicly.

What is working is when states get to decide what material to provide in schools. That includes required curriculum and what books they will buy and offer in classrooms and libraries. So the state can teach (or not teach) whatever they want within the confines of their own schools, but there's nothing they could do if, say, someone was to set up shop on the sidewalk across the street and hand out free copies of Gender Queer to any students who walk by. Nor could the fed, as it stands.

So we've led our horses to water, but how do we make them drink? How do you convince the students to want to pick up that book and read it for fun, and how can you help them understand what it all means when the critical reading skills for queer literature are not being taught?

Remove books and papers from where? The government in the US has influence on this, for sure, but there is no mechanism for the government to interfere with the private ownership of literature
