The Carroll Independent School District in Southlake, Texas, is cracking down on the books teachers keep in their classroom libraries, drawing protests from educators who say the guidelines amount to censorship. The move comes just days after the Carroll school board reprimanded a fourth-grade teacher who had kept a copy of This Book Is Anti-Racist by Tiffany Jewell in her classroom library following complaints from a mother who said the book violated her family’s “morals and faith.”
