No one owns lies. Lies are not literary works. Lies aren't fiction.
Fiction is presented as such by the authors precisely to avoid it being seen as lies instead.
This is especially so with purported works of history. A purported work of history full of lies is neither history nor fiction, but simply lies.
If one lifts lies from another source and repeats them, one simply becomes a liar, plain and simple. Its no different than spreading outrageous false rumors one has heard by word of mouth, which is called slanderous gossip. Just because someone told you outrageous lies and you didn't bother to chec their veracity does not relieve you of guilt in lying.
Which of those things is not true?
