Lies and revisionism in entertainment media is what creates folk stories and folk heroes. It's where a big source of our culture comes from. Folk stories aren't hurting anyone. Take Abraham Lincoln: Vampire Slayer for example. I'm fairly certain Abe didn't kill a single vampire. Or John Henry, the steel driving man. Maybe he did beat a steam drill and die with a hammer in his hands, but he probably didn't. Talk to all the blues singers who tell tales about Stagger Lee killing Billy Lyons. I'm sure they really care about the facts and would love to know that Lee wasn't actually 10ft tall and and that he didn't actually meet the devil himself.

Even dating back to Odysseus, did he actually meet the sirens and the cyclops and see his men turned into pigs? Probably not, but it's a damn good story. You'd have to prove malicious intent before anyone could entertain the idea of folk stories causing damage to anyone.
