Is There a Ban on Books in Schools?

I mean, the whole prospect of banning books in America in the 21st century seems on the face of it. Where do we know that countries ban books is in authoritarian regimes? And there is a smack of that happening in schools in the United States at the moment. I'm just saying it's like in Florida, Rhonda Sandis scares the hell out of teachers and librarians. That is the entire purpose of this.
