You're welcome. All you have to do is remember what a novel is -- and is not.
I guess you're a little concerned about it yourself, or you wouldn't be participating in this thread.
This entire discussion is predicated upon the fact that many, many people believe the history they read in novels. That is empirically true, no matter what you and I think about the intelligence level it implies.
If you heard that someone did a play in your child's classroom which taught that America was stolen from the rightful owners, would you correct that by injecting a contrary interpretation of history into your child's thought life, or would you simply take the attitude that "everyone knows that drama is not history"? Of course not.
So your entire response to this issue, that we just have to remember what a novel is and is not, demonstrably misses the point, which is that great numbers of the public do not so remember, and therefore must be reminded.
