What, like the Bible?Except the alt-right is censoring books, literally censoring. Not in a "this story smells like crap, and virtually no backup to the claims has been provided" moderation, but actual elimination from the schools.
It is long established constitutional law that parents have the the right to guide their children's education. And teachers are not free to saying anything they want to their captive audience.Actual legislation to ordain parents as overseers of teachers and limiting what teachers can and can't say.
