Scenario

At the end of her humor and commentary, the Annoyed Librarian recently asked an interesting question. If a patron were to come into a public library and ask a librarian for information stating Barack Obama is a Muslim (or substitute the misinformation of your choice), what is the proper librarian response? The (mis)information is out there and easy enough to provide. Should it be provided without comment? Provided with comment? Should a lesson on information literacy be provided instead? What is the role of the public librarian in this instance?
