Defending Captain Underpants

There are many banned books; some are banned with good reasons, others not so much. I can understand why books like The Joy of Gay Sex is banned, but I do not think Captain Underpants should be banned. I think it is an incredibly dumb book, but it doesn't have anything in it that is morally wrong. There are many grammatical and spelling errors in it, but it can get children reading. Captain Underpants may just be a gateway book. Children will start reading Captain Underpants because it entertains them, which may lead them to reading other, more educational books.
