In dozens of states across the nation efforts are underway to influence, even intimidate, school board members to restrict what can be taught, and what library books can be available, to public school students.

In South Carolina, for example, school boards are considering proposals to ban a long list of books from school libraries because of parental objections to their content, whether it involves the discussion of sexual identity, racial disparities, or other "controversial" topics. In Horry County, home to the resort community of Myrtle Beach, the county school board meets January 23 to consider such requests involving some 77 books.

Behind the drive to restrict library books and subjects that can be taught are activist conservatives, including Moms for Liberty, which says it "is dedicated to fighting for the survival of America by unifying, educating and empowering parents to defend their parental rights at all levels of government."

"This is a very small, radical faction," says Josh Malkin, legislative advocate with the American Civil Liberties Union (ACLU) in South Carolina. "Polling shows that folks on both sides of the aisle see book bans for what they are: a very dangerous attack on one of the core values of American democracy. This is not Democratic, it's not Republican, it's not conservative, it's not progressive. This is radical. This is authoritarian, and this is dangerous."
