PolitiFact deals out a 'mostly false' rating on banned books that is itself mostly false

Here goes PolitiFact again, showing how what would seem to be a straightforward system for rating statements—true, mostly true, half true, mostly false, false, or pants on fire—is often unreliable and frequently biased. Last week, the pop star Pink held a banned-book giveaway at her Florida concerts to protest the state’s recent restrictions on books in classrooms and school libraries. To promote the effort, she tweeted a list of books “that have been banned from schools in Florida.” PolitiFact has now rated that list as “mostly false,” straining the definitions of the words “mostly” and “false.”
